@nem it was decade+ ago when I've been looking at DIMM 1.02 firmware disassembly, so I can't remember details... but, in theory, if DIMM<->NAOMI interface have commands like POKE/PEEK to DIMM RAM - it might be possible to upload some our code there and patch DIMM firmware in RAM to make it run...

I have a photo of Dirty Pigskin cart which was dumped back in the days and it's 837-14695

no, not in near time at least, uno2 will require more time and work as it have ~15 or so data chunks encrypted (uno1 had only one so was relatively quick task)

errm, I do not imagine how game test mode may "seems to be fine" if it's not cracked and hang for me. are you sure you telling the truth? anyway, here is fully cracked Touch de Uno. make sure to mirror it if it's needed for you, the link will not be active for a long time...

https://mega.nz/file/gR1WgJAQ#8HRx6PKkL-3AWPv5cCINT5_umNOu17kIMBqx1yWxbyA check this if it boot to title in game mode at least (test mode is not done yet)

I no idea, but protection was cracked in this game, so it's something else

which exactly touch game you need? Naomi games uses at least 3 different touch screens / its controllers - Touch de uno 1/2, Manic panic ghosts and Touch de zunou, Starhorse.

good luck with that but notice suchie3 have several data chunks encrypted and compressed using cart protection chip, so this should be handled in a crack netboot conversion

isn't it mahjong game and require special control panel to play it?

AFAIK this has been already done, one person hired chinese firm to RE Hikaru PCB, and it has been done, all the layers. I have all the files, but idk if I'm allowed to share them...

for sure I've did CDJ2 prot crack awile ago, but I haven't access to my home pc right now...

@mzmuscle4 NAOMI games in general set to Free Play via BIOS Coin settings, including HOTD2, they doesn't need any patching. only few of NAOMI games is buggy in some way and not handle BIOS coin settings properly.

thank you for dumping it and checking

hard to say, 1st two byte difference is in some interrupt or exception handler, as I see it ended with RTE. not sure about last byte. but it's boot ROM, and it may affect only boot functions - loading game from CD, programming SIMMs, etc. changes in boot ROM doesn't any affect running games...
