Dedicated IGS/PGM Board ROM Swaps

Post by shmuppyLove »

How feasible is a ROM swap on one of those dedicated PGM boards? I assume there is some sort of BIOS protection on them ...

Easy peasy. Program ROMs require re-encryption and graphics/sound roms just need to be desoldered and resoldered.

Though, not all of them have the same protection chips. If you just want to switch between CAVE games, that's all that's needed.

Cartridge as in a cartridge for the pgm motherboard? That sounds interesting. Does it run identical to a real doj bl board? And whats the price?

Does it mean an Espgaluda board (which is of much lower value) can be converted into a Ketsui board?

Is the PCB number (PCB-0418-00-FX-2 for Ketsui) printed on the PCB the only distinction between the two boards?

Yes. Well, that and the graphics/sound ROMs which need to be desoldered and resoldered with the new ROM data.

Also the decryption key is different, but that's not a big deal.

Would a rom cartridge of ESPGaluda & Ketsui be possible? If so it would be very tempting to buy a PGM mobo...

That's true..
I checked your website, and not to be rude, but it could use a make-over... Maybe we could work something out? :wink:
