I will do, as I don't think the two models have any difference in the cartridge caddy sizing, the UK consoles are literally US shells with different logo sticker on it. I think the issue was obviously a costing one to keep it cheap, but I think the yellow section needs to be longer to guide the cartridge in as I struggled to get the pins in all the way. Guess im doing a crash course in soldering and understanding a multimeter XD Edit: I'm basically autisticly meltdowning because it was working fine until I opened my console, I'll contact her when I'm fit to communicate with people again XD thanks for the advice again e5frog...

Mikebloke Posted August 2 Share Posted August 2 Ok posted on the Backbit Forum for now. In the meantime I have a first version ready for Submarine for the Channel F, this is a first release version, I imagine I'll get a manual and updates out tomorrow. Download here: subf8.bin How to play: 1 key on console: player is submarine (blue), destroyer (green) is automated 2 key on console: player is destroyer (green), submarine (blue) is automated 3 key on console: player 1 is submarine (blue), player 2 is destroyer (green) All games have escort (red) automated. Left and right to move your respective ship on the screen Plunge / Push down shoots missile Submarine player has to shoot either Destroyer or Escort for 1 point Destroyer has to shoot Submarine for 1 point First to 15 wins the game, game can be reset anytime, either in game or at end of game with 1,2,3 keys on console as above. Game plays in "attract mode" on boot up Things to do for final port version: Slight pause and flash at hit (all ships) Sound (like usual, the last thing I touch) Manual in usual style Fixing up some graphics so its more stable looking Changing the positions slightly for TV Fixing the screen wipe to light green to get grey (I'm wondering whether wiping whole screen grey then trying to get light blue makes more sense, I'll play around with it tonight / tomorrow - the thing that will take the longest to do the least change). Possibly including one more game type (no red escort ship) The original PC-50X game had a space ship game included as well, but its much more dull as it involves shooting a missile that fills the line down making it extremely easy to avoid. The second space game the ships are hidden until firing (again, making it incredibly easy to dodge). Like all my ports, I always plan a form of "plus" version someday to make it more challenging and fun, but my main intention is just to port weird or similar timeframe games to the Channel F in as natural a form as I can. 1 Quote Link to comment Share on other sites More sharing options...
Mikebloke Posted August 5 Share Posted August 5 Updated version, this may be the final version but I think there is still some tweaks needed. Download here: subf8.bin Ships flash colours, pause movement and also cannot fire new bullets when hit Two sound effects, one for being hit (all ships) and for submarine missile (feel free to mute!) Sped up the display of ship movement to avoid as much flicker Fixed a small bug where the Destroyer missile goes blue on the submarine line Increased the range of movement on the right hand side to compensate for varied ship sizes What hasn't' been done: From original game: The two player game in the original game is actually escort free, so just the destroyer and submarine, I could do this potentially 4th game type of the hidden ships unless firing - my next thing is can I add this in easily and potentially keep it in 2kb, I will see. Ambient "submarine" sound of a sonar ping like noise - I think I've done well to get the other two in, even though they are grating on the ears, not likely to be able to create anything that can run while other things are going on For Channel F: Adjustment for tv screen - haven't looked into it yet. Fixing the screen wipe. Tried a number of different things, including wiping screen grey first and painting lower bit light blue, it doesn't like it, so the green wipe first will remain (a pain, not sure if this is an emulator only issue and would be fine on a console). Manual in the Channel F style - if only because I'm working on another little game I want as a screenshot for the "coming soon" section. I've worked to keep it within the 2kb range, there is no reason not to push it beyond it other than challenge. I think with some optimising I could still do the above todo list and keep it within 2kb. 2 Quote Link to comment Share on other sites More sharing options...
Mikebloke Posted August 9 Share Posted August 9 (edited) Got round to finishing the game as much as I'm likely to do for now. Hope you enjoy it! subf8.bin INSTRUCTIONS FOR SUBMARINE.docx There is now a "night sea" mode through button 4 on the console which switches the game to black and white - ships only appear when firing (or being hit). I have attempted to adjust the distance to the sides to make it TV able - no way to test this right now unfortunately This means there is a smaller moving / firing area so its not so wide. Manual is now done as well. I've kept the game in 2kb, no real reason to restrict it, its more just an achievement for me and can be cut down more than this, I haven't tried to optimise much, but it could be. I've kept the Escort in the standard 2 player mode, the reasons for this is that in the original Night Sea mode, the Escort is there and appears when the Destroyer fires. While it might be "fun" for the destroyer to not have a indefensible target for the Submarine player to hit on its side, I felt that a 2 ship firing situation gives no real tactical gameplay and a reason I've never been keen on implementing it in etiher this port or the Atari 2600 port I tried to do years ago. Essentially you just end up trying to fire on each other but get to move out the way first. This way, although the Submarine player does have a very obvious advantage (the Escort ship is always predictable route wise, and the Submarine is a smaller ship to hit) it also gives the destroyer a chance to hit the submarine as that player tries to focus on the escort. In tests with my children, the age difference helps even out the Submarine advantage and it is possible to hit the Submarine player fairly often. However, Submarine as a game is always a biased game in favour of one player. Rather than doing the modern thing of "evening" it out to be "fair", I've kept the spirt of the biased game by allowing Submarine player its significant advantage. Any plus version likely have buttons change game elements so it can be more versatile with its options (2600 style), escort on/off, one player or two player mode, hidden ship mode on or off etc. Edited August 9 by Mikebloke wrong words when children are looking over my shoulder 2 Quote Link to comment Share on other sites More sharing options...
e5frog Posted August 11 Share Posted August 11 (edited) There should be a proper shell made for the backbit to fit better. Instead of the "handy to move around between systems"-option a more permanent design would be nice. Something larger, videocart-looking to dock into or a replacement shell entirely for the backbit. I might get one as well if I happen to fall into a pit of money. Why are the binaries 2046 bytes and not 2048? Only took a quick look, hoping to get a game in later.

e5frog Posted August 25 Share Posted August 25 .... everyone needs to get a BackBit... it's actually cheaper $134 with the adapter. I would need to pay $8 fee and 34$ tax - and $20 shipping - so only $196, feels like it will never happen. 😢 I could ask a friend to ship it though - and save $42 by escaping tax... https://store.backbit.io/product/backbit-pro/ If anyone feels the need to sponsor me with a BackBit I'll make a proper Channel F cart shell 3D drawing for 3D print. That baton she's come up with is an eye sore. BUT, some nice design to put on the shelf, increasing the Channel F library IS pretty nice. 1 Quote Link to comment Share on other sites More sharing options...

I feel that those are two different markets to be fulfilled. Of course a multicart is a highly useful little thing, a cart that you can keep plugged on your console to play whatever you want, whenever you wish. That’s the “player’s market”. I really should aim for a copy to myself. But a boxed copy of a dedicated cart, the “collector’s marked” is something else entirely - the fetish of having a beautiful thing, carefully crafted. And you’re not forced to pick a side: you can have only one of those, or both. There’s multicarts for a lot of systems, like Atari 2600, Coleco, NES, Vectrex… you name it. But the collectors still hunt down the boxed games. 🙂 1 Quote Link to comment Share on other sites More sharing options...
Ashevent Posted August 26 Share Posted August 26 (edited) I like owning all the official carts and a multi-cart for the rest unless there's something super awesome to me which..dammit, e5frog's stuff is so nice i do buy the separate carts too..lol. but truth be told, the multi-cart is what i use the most for the Fairchild and my verctrex. to each his own, nothing wrong with any way you wanna play or collect. i dont think im getting the plus of a 3d printed backbit is it cheaper to update with a new board versus buying a whole new multi-cart or that is can hold multiple multi-cart boards depending on what you wanna play thats the bonus?

poppalarge Posted August 27 Share Posted August 27 The main benefit of the backbit is the price. You buy the backbit itself for like $130 - then you buy the adapters for like $20 each which stay in your various consoles/computers. So instead of buying multiple multicarts for $100 or $200+, you buy the adapters for $20. You just move the backbit itself from adapter to adapter, using the same SD card to hold everything. Then a secondary benefit is you can easily update the romsets you have on the SD card in the backbit. Like lazzeri got at earlier though, it's way more useful for the player's market as opposed to the collector's market. Quote Link to comment Share on other sites More sharing options...

e5frog Posted September 3 Share Posted September 3 I'm selling two Multi-Carts for $150, it's the last two I have chips for atm. Need to raise $300 for car repairs (left back wheel bearing). I'll give you guys a chance to reply before I shout out about it. About 2 weeks before delivery, so no long waiting times. Let me know. 1 Quote Link to comment Share on other sites More sharing options...

Ugh, sorry to hear about bearings! I have one of yours already. I'll check back, and If no one from her wants one I'll do a shout out on IG and hopefully find a buyer.

e5frog Posted September 11 Share Posted September 11 (edited) I experimented with stealing frames from Leaderboard on the C64 emulator WinVICE. I took half the frames and made a set of 16 and changed to Channel F colors. Then wrote a cmd program in C++ to filter just the changes from a previous image and got a set of black bmp-images with a little colored scribble on them. Had to take the size down a little and shrink height as the Channel F pixels are tall. ... ... Stripped the header of the bmp-file and translated the index colors for green, red, blue, background and clear into 0, 4, 8, C and F (because colors set into ports corresponds to $00, $40, $80 and $C0). The conversion program does both the bmp preview of the frame change and the binary file with the Channel F image data, just drag and drop two files (equal in size, my palette layout). So I now have graphics data with two pixels per byte that I can draw with my new nibbledraw code (very small changes to "multiblit"). For clear it just skips the pixeldata transfer, so present graphics stay there, just like the "blit" code does if "clear" color is set. It's slightly faster than "multiblit", as it doesn't need to decode colors from two bits - but it requires double as much data (which is normally not a problem). My example could easily have the graphics compressed (should there be a need for it) a lot with a simple routine and unpacked to RAM, there's a lot of empty space in the frames. Move controller in a direction to swing - it's just the hitting, nothing else fun (yet). Having the courses drawn up from polygon data would have been really neat... 2023-09-11_38_14_Leaderboard.bin Edited September 11 by e5frog 2 1 Quote Link to comment Share on other sites More sharing options...

Dopy25 Posted September 21 Share Posted September 21 Anyone know which VR this is? It's in a early model channel F and there's only this one. No other VR. Would that make it a 7805? Or is this a 12v VR? Symptoms of this console is zero signs of life. No red LED, but there's power to the switch. Volts seem low at the VR, so I'm guessing it failed. I want to replace it, but I don't want to use the wrong one. Google was no help for the ua77m12 and even less help when adding the rest of the info. 1 Quote Link to comment Share on other sites More sharing options...
e5frog Posted September 21 Share Posted September 21 It's a 7812, 12V regulator. Check diodes as well, they go pretty hot. 1 Quote Link to comment Share on other sites More sharing options...

Is there any way to get those in the original footprint, or would I open them or remove the whole thing and replace them? Thanks for the info on the 7812. I wasn't sure if that was it, or if there was something whacky involved. 1 Quote Link to comment Share on other sites More sharing options...
e5frog Posted September 23 Share Posted September 23 Not sure what you have in yours, they're often four loose diodes soldered to the board. 2 Quote Link to comment Share on other sites More sharing options...
