Maybe we can get Tamashii running on there too!Seems white/black label is certainly possible as well:

Tamashii is PGM2 only isn't it? I don't think you'll be back porting that to PGM1Maybe we can get Tamashii running on there too!
That is my thinking, because as far as I can tell the graphics PCB is just a dumb ROM board, so ANY game should work with big enough ROMs. My plan (unless someone beats me to it, which would save me some work) is to just pick whatever ROM type is easiest to get.The Lydz Graphics PCB is NOT a custom PCB. I was expecting this to be custom similar to the program PCB but it's actually a PCB NO-0213T which is from Knights of Valour Super Heroes. This is really interesting because it means that the Same Graphics PCB design is compatible with all 3 cave games. it seems to me that would make designing a custom Graphics PCB (maybe even one that supports 27C322 DIP EPROMS, so you wouldn't have to do power conversion) would be a better option than converting.
It is, but it's just a different arrange mode of the game. It's not a whole new game or anything. So maybe!Tamashii is PGM2 only isn't it? I don't think you'll be back porting that to PGM1Maybe we can get Tamashii running on there too!
It has been hinted at some pointHmmm, PGM Cave conversions have been out for such a long time now.
I wonder if DS will do a PGM multi some day.
AFAIK 27C322 (32Mbit) is the largest DIP package EPROM you can get, but it's 16-bit only. the 27C160 (16Mbit) is the largest DIP package EPROM that will work in 8-bit mode.as far as I can tell the graphics PCB is just a dumb ROM board, so ANY game should work with big enough ROMs. My plan (unless someone beats me to it, which would save me some work) is to just pick whatever ROM type is easiest to get.
yes, his Killing Blade conversion had the ASIC, M-ROM and one of the PALs completely removed. It looks like the remaining PAL might be custom and we don't know if there are any jumper wires on the PCB either.there is still a mystery, and that is the lydz's espgaluda using a real PRG pcb running without the ARM chip, different from that custom one showed by twistedsymphony.
I was poking around the mame driver a bit today and there were a few things I noticed.I would love to see what they did to disable the ARM.
so I wonder if these ROMs are basically patched by appending the single board bios into the program ROM so it can overlay the cart system bios.// the program rom in the cartridge actually ends up mapping OVER the motherboard bios rom, you don't get the PGM splash etc.
killbldp:ROM_LOAD16_WORD_SWAP( "u18.107", 0x100000, 0x400000, ...
ketbl:ROM_LOAD16_WORD_SWAP( "v300x.u6", 0x100000, 0x080000, ...
so the modifications to the pal on killing blade are probably the same as what needs to be done on KOV2.ROM_LOAD16_WORD_SWAP( "ketsui_u1.bin", 0x000000, 0x200000, ...
ROM_CONTINUE(0x000000,0x200000) // first half is empty, use 2nd half
no, DDP2 only exists as the officially released version; there is no "bootleg"/modified version.4. someone decrypyted DDP2 and re-encoded it with the KOV2 key
maybe it can, but in this case no, because in all existing scenarios it remains unmodified.5. maybe the ASIC can be configured to a pass-through mode for development?
Nice progress. I'm interested to see where this ends up.I attached a new version of the schematic
If I didn't get the feeling that'll sell for over $1000USD, and if not for the fact that I don't want to give Scramble any money, I'd say we should buy it and dump it.Seems white/black label is certainly possible as well:

I guess I will look for DIP sized ROMs at the start, as I'm mostly interested in the games that have no official release. SMD sized packages are a pain to solder and program. Though I'm sure someone can make an SMD variant once everything is documented.if you plan to go with DIP sized ROMs on the Graphics board you wont be able to support any of the beat-em ups, fighting games or Demon Front, they just have so much graphic/sound data that you wouldn't be able to physically fit the chips on the board without going SMD. you could definitely make one that supports all of the SHMUPS though, you'd be looking at 7 total 27c322s, 1 for sound, 4 for sprite color data, and 2 for sprite mask data. the puzzle game use even less data so those would be covered too.
If you mean "no official cart release" then there are 3I'm mostly interested in the games that have no official release.
That same conversion can also be done on this cart: Any PGM Conversion info out there?I'm not sure if the 27c322 for the audio rom will work, as the mod uses a MX29L3211 which has a 4Mx8 mode while the 27c322 is 2Mx16.
