You leave them floating and don't do anything with them.

yea use skull and crossbones. straight solder in a 27c512 chip for the CHR and wire the PRG like a TLROM. thats it, pretty simple OK will do. Was just trying to have more options as I come across Rolling Thunder alot more than Skull & Crossbones locally. Thanks for the info for sure. I'll just ...

Prototypes are by definition unique. If you're sure it's "just another mapper #x" game, then all you need is the pinout of the Tengen MaskROM. I have no clue, all I know is that Skull & Crossbones is a proper donor for standard eprom modification use and the Rolling Thunder can also b...

no love?

Hey,

I was wondering if anyone has the schematic for the wire job needed when turning the rolling thunder version of the the tengen "rambo" pcb into a suitable board for use with the xybots proto please.

Thanks!!

Bump, changed to SNES version as I've opened up my Genesis gun and the SNES footprint is on the board I just have no clue what goes where.

bump in hope of some 2010 love AKA still looking for the Genny Justifier pinout

Happy New Year Everyone!!

Hey,

I was wondering if anyone has the pinout for the SNES Justifier gun? I need to know the connections at the PCB inside the gun. I'm looking to find out as I plan on re-wiring one to use on the Yobo FC3.

Cheers

Too much work for so little reward IMO. Maybe someday if I'm bored and feeling adventurous I'll have a crack at it I suppose.

MMC1 IC pinout from rom.txt A known SNROM game: The Legend of Zelda ( PCB pics at bootgod ) The SGROM wiki page implies that if you take the PRG RAM off an SNROM board, you have SGROM. Take the CHR RAM off too, and you have nothing. The CHR ROM bank bits out of the MMC1 just lead straight off the t...

Hey, I got a defender of the crown by accident today (thoought it was SN-ROM, not SG-ROM my bad I know) but anyhow what I was wondering is with the CHR RAM removed what kinda PCB would this board be equal too? Just a normal MMC1 board? As in I could wire up an EPROM to the CHR spot the same as any o...

NES & SNES are fairly new waters for me. My forte is with the Atari machines

All of those chinese junk programmers made by Willem, Top & the clones of them are not worth the cost of shipping let alone paying for such crap. If you want a burner that isn't a POS your gonna shell out a couple hundred bucks at least. I wouldn't recommend it as "good", but my ~$60 ...
