I think I'll continue development anyway. If nothing else, I can experiment with other features If yours is cheaper and/or a doable DIY project then it will still have an appeal. 1 Quote Link to comment Share on other sites More sharing options...

I managed to boot an image but not getting any emulation running. Ideal would be a finished image, that starts Channel F ASAP after powering up. A tutorial for total noobs is needed. What model Raspberry Pi do you have? 1 Quote Link to comment Share on other sites More sharing options...

Not sure about that, the backbit is for "everything" and costs thereafter, there's no image of how it's supposed to be used. With that many supported systems I also wonder how well tested it is, text says it supports bin to 62kB - I wonder what has been tested. A dedicated flash cart is a much better product, with the DIY-person in mind. I think everyone in the community would like you to do that. If anyone gets the backbit (when it's available) to use on the Channel F, please share your disappointment here. Quote Link to comment Share on other sites More sharing options...
evietron Posted March 5 Share Posted March 5 My guarantee is that if your game does not work on BackBit, I will work to make sure it does. 2 2 Quote Link to comment Share on other sites More sharing options...

That is one hell of a commitment! Have you done much testing with the Channel F adapter, has it got full compatibility? Does homebrew run on it fine without any issues? In defence of @3DMAZE the prototype version I have is still amazing even with the few issues to iron out, mostly 'PAL' system issues. Its significantly stepped up some elements of my development for the system and there is virtually no issues on the games I've developed so far, and a lot of the others run too without issue even on a European system. 3DMaze is still the first to get practical, user friendly rom loading experience out there even if its not yet general release. I'm hoping we don't need to keep sacrificing donor carts now e5frog for new releases now we have a 3D printed solution for game cart cases (at least!). I still need to convert to the new CHF format at some point, when my brain can take some new information in. 1 Quote Link to comment Share on other sites More sharing options...
evietron Posted March 5 Share Posted March 5 It runs all titles I could find. Exposed memory is from 0x0800 to 0xffff (i.e. 62K). The format is BIN, although it would be possible to add support for another format if I can see a spec. Any ROM memory that is unused can be used as RAM. 1 1 Quote Link to comment Share on other sites More sharing options...

Sounds great, how do you have time to support all systems and users? 10 hours ago, evietron said: It runs all titles I could find. Exposed memory is from 0x0800 to 0xffff (i.e. 62K). The format is BIN, although it would be possible to add support for another format if I can see a spec. Any ROM memory that is unused can be used as RAM. Does Maze and Hangman work? They use RAM through PSU ports, not mapped on memory map. The Maze version on the Multi-Cart has been modified to use mapped RAM but I never got around to fix Hangman (nor Rat' mal) - so you can't add your own words. Does it work on PAL machines as well? @3DMAZE and I made up a file format to be used with the flash cart, would be great if it could be supported. https://github.com/ZX-80/Videocart-Image-Format What parts are used that aren't currently in stock? As it's not available buy at the moment. IIRC the adapter is $24, is this the final version of it? 11 hours ago, Mikebloke said: @3DMAZE I'm hoping we don't need to keep sacrificing donor carts now e5frog for new releases now we have a 3D printed solution for game cart cases (at least!). I made the shell CAD drawings years ago but it has been a lot cheaper getting real shells than having durable and good looking enough shells bought from a manufacturer. 3DMAZE did some nice ones, I think he had them made at school. I'd love to have proper new shells made though, removing labels and cleaning shells probably takes half of the time when making a cart release. 1 Quote Link to comment Share on other sites More sharing options...

e5frog Posted March 20 Share Posted March 20 Hope I didn't scare @evietron away, I see I forgot to @ her in my reply. Hope the BackBit's availability an my temporary wealth coincide at a later date. 1 Quote Link to comment Share on other sites More sharing options...
poppalarge Posted March 27 Share Posted March 27 Hey everyone! It's been awhile since I checked in here. Wanted to do 2 things: 1 - I have the BackBit for the Intellivision and the Colecovision, and both of them have worked with every game I've thrown at them so far. I don't develop anything though, so I can't vouch for the homebrew development experience. 2 - I've listed my entire Channel F collection for sale over in the marketplace if anyone is looking for anything not named Checkers. 2 1 Quote Link to comment Share on other sites More sharing options...

Post the ROMs you want supported there, and I'll do my best. Just received a big batch of chips, so orders are only dependent on build time now (although there is a 1-2 month backlog currently). 1 Quote Link to comment Share on other sites More sharing options...

Just received a big batch of chips, so orders are only dependent on build time now (although there is a 1-2 month backlog currently). @evietron If memory can be used from $0802 (after the necessary "U" and the wasted byte) to $FFFF as ROM or RAM, there shouldn't be a problem if the SMI emulation is complete (enough) - or however it's solved. Being able to run the Multi-Cart would be neat - as it now-a-days does in MAME/MESS. I imagine re-programmable quick start options would beat the fixed ones the Multi-Cart has (hold button(s) to start a program immediately after reset). I will post requests if I get one. Still hoping @3DMAZE will solve the problems with the flash cart, currently "anyone" could put one together that works with almost everything if running it on an NTSC machine. He has other priorities as well of course (don't we all). I'll get back to the Videocart-29 production again... shipping three more today. 1 Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted April 15 Author Share Posted April 15 I decided to test my Channel F console after a period of not using it. I was surprised to find out the Multicart was not in either console! I don't know why I would have taken it out. I searched and searched but could not find it. I have a near-complete collection (only missing Checkers), I'm also at a loss to where carts #23 and #25 went. Great. Another activity to do when it gets warmer and when I am not asleep during the day: Rummage through the garage and try to find those. I'm back working on Adventures of the Stalk of Celery. I thought I'd try something different: A port of my Game Gear game I just finished up. Quote Link to comment Share on other sites More sharing options...
EdgeOfPortal Posted May 2 Share Posted May 2 https://www.ebay.com/itm/195742135802 Another Checkers, but no box on this one. Quote Link to comment Share on other sites More sharing options...
