Flashback 2 Website - Cartridge Mod Hack

[Flashback 2 Website - Cartridge Mod Hack]

I got it! That was it AJ... I just needed to move the wire to the other side of C4.

Something so simple.... oh well, live and learn... which was the whole point of me trying this anyway.

 

Again, thank you for your help.

 

Thanks for your help too, Curt.

Well, I guess I hit a "bad" batch (as far as modifying them), because I bought a second one, and before I touched anything, I checked J40 and C4 and they have continuity between them on this one too. So it's really no use I go any further.

Oh well, I got most of what I wanted out of this project, which was to learn.

 

Maybe I'll try it again with the Flashback 3 if that ends up being an option on that one too.

 

Thanks again for you help guys.

Should I have continuity between the black wire's original point at J40 and the new point at the top of C4? No matter which one I have the black wire hooked to, I still see the startup screen for the Flashback 2 (castle). And when I add the jumper to J3 (connecting the left and right sides), all it basically does is sort of scramble the title screen. Now, if I plug in a cartridge, I'll get a whole different kind of scramble, though that scramble will slightly change when I attach the jumper.

 

Any ideas or thoughts on this would be appreciated.

 

And just to double check, if you were facing a cartridge connector, already in a machine, I wired bottom left as 1, bottom right as 12, top left as 24, and top right as 13.

 

24-----------13

1------------12

 

Is this correct? I also tried:

13----------24

12-----------1

 

just to see, but that didn't work either.

 

I may be in over my head with this, but I figured I'd give it a shot.
