antron Posted February 4, 2007 Share Posted February 4, 2007 Are Pixelspast homebrew PCBs compatible with a Flashback 2.0 mod? I get just a little blip of recognizable graphics before the screen goes blank. I am using a 4K EPROM in a RevB homebrew board with a RevB Flashback 2.0. Normal carts work fine. Any ideas?

Albert Posted February 4, 2007 Share Posted February 4, 2007 It should work fine, although there are some games that are incompatible with the Flashback 2.0. What game are you trying to play? ..Al Quote Link to comment Share on other sites More sharing options...
antron Posted February 4, 2007 Author Share Posted February 4, 2007 You are right. I was trying swoops, didn't work. I just got yar's revenge to work. Thanks. I have been going crazy. I was going by the pinouts on the pcb to wire the mod, so I had the carts in backwards all day. Got it all straight now. Quote Link to comment Share on other sites More sharing options...

I think there is a list somewhere on the forum of games known not to work with the FB2, but at quick glance I was not able to find it. Does someone else know where it is? ..Al Quote Link to comment Share on other sites More sharing options...

I have 4 and 8 kB boards to test with. Edited February 5, 2007 by antron Quote Link to comment Share on other sites More sharing options...
Zonie Posted February 19, 2007 Share Posted February 19, 2007 Hmmm... That photo gives me the idea to just install a ZIF socket on the little bugger. Quote Link to comment Share on other sites More sharing options...
Thomas Jentzsch Posted February 19, 2007 Share Posted February 19, 2007 I am not much surprised that SWOOPS! doesn't work. There are some very nasty coding tricks to optimize for space inside. Quote Link to comment Share on other sites More sharing options...
Shawn Posted February 19, 2007 Share Posted February 19, 2007 (edited) Hmmm... That photo gives me the idea to just install a ZIF socket on the little bugger. FB2 software dev kit? Damn straight! Good idea!! That way you know for sure if you program a game it could be thrown at atari for consideration for the FB3 EDIT: FB2.5 I mean (the portable) Edited February 19, 2007 by Shawn Sr. Quote Link to comment Share on other sites More sharing options...
antron Posted February 26, 2007 Author Share Posted February 26, 2007 Hmmm... That photo gives me the idea to just install a ZIF socket on the little bugger. I was going to do that, but I would be restricted to one or no bankswitching type. I plan on putting ZIFs on the pixel's past PCBs. Quote Link to comment Share on other sites More sharing options...
Albert Posted February 26, 2007 Share Posted February 26, 2007 The finished product: I opted for the laparoscopy over the full surgery That is beautiful, I love how you cut a hole in one of the grooves. That's a pretty old PCB you have there, for the past few years they have had red soldermask. ..Al Quote Link to comment Share on other sites More sharing options...
Thomas Jentzsch Posted February 26, 2007 Share Posted February 26, 2007 That really looks great. Now I wonder if there is a more or less complete compatibility list of the FB2? Quote Link to comment Share on other sites More sharing options...
antron Posted February 26, 2007 Author Share Posted February 26, 2007 (edited) Thanks guys. I used an old floppy connector. The ribbon cable is removed and replaced with Kynar wire for easy soldering. The wire fit into the connector's teeth perfectly, and is secured with hot glue. You can see the DTDP switch in the back. I'm not sure what gauge wire it is but it looks pretty thin, and much larger would've worked as well.

antron Posted August 10, 2007 Author Share Posted August 10, 2007 (edited) I decided to give this to a friend as a graduation gift, but rather than give him a bunch of eproms, I built him an eight bank multi-cart. Loaded with 8K and doubled up 4K roms. Consists mainly of an altoid-like box and hot-glue. I was having trouble with pull-up resistors, so I used double-throw switches and fed the address lines pure Vcc or ground. I cut traces and soldered to the pcb so I could easily swap out the eprom.

Swoops is having trouble with Chimera too. Sooner or later Delicon needs to go over what's involved there. Quote Link to comment Share on other sites More sharing options...

If you describe the problems in detail, I might be able to give some hints about the reasons. BTW: The name is "SWOOPS!". Quote Link to comment Share on other sites More sharing options...

If you describe the problems in detail, I might be able to give some hints about the reasons. The game doesnt appear to have a problem when compared to Stella. The bouncy game works and the helicopter game works, but the third game doesnt do anything. A smiley face just sits on the middle left side of the screen; moving the switches and joystick doesnt do anything. Vern Quote Link to comment Share on other sites More sharing options...

Vern Well, there is a slight issue in 'Splatform' with Stella, but it's due to a TIA bug in Stella itself, not the game. ...but the third game doesnt do anything. A smiley face just sits on the middle left side of the screen; moving the switches and joystick doesnt do anything. You know that this is a paddle game using the right port? Yes, but you'll have to manually set the mouse to paddle 2 for it to be detected (the default for mouse is paddle 0). You can set that by pressing 'Ctrl-2'.

Funny because I actually tried plugging a set of paddles into the VCS. Silly me ... I used the left side.
