you're welcome worth to mention it's possible thanks to work of me and @brizzo several years ago, when we reverse engineered checksum protection performed by Atomiswave ASICs, so now it's possible to hack/edit AW game binaries and run them on real AW, or create some homebews. a bit documented...

have you tried without -ata switch ?

it's by design, it's same in any emulator with recompiler, due to block-based nature sorry, there is no such feature, in later versions at least

FWIW - how works protection in Capcom Medalusion games: code read 20bytes from very beginning of CF card (scrambled game name) then XORing them with 20 bytes of ATA IDENT reply starting from offset 0x14 (SN# area) then XORing together these 20 bytes each other, result byte should be 0.

yes, he dumped ROMs and CF yesterday, but was unable to dump ATA ID properly. it's not super big problem, because this game, same as Pingu, expects SN# area (20bytes starting from offset 0x14 in ATA ID) to be simply filled with spaces (0x20), and I handcrafted one which makes game to boot...

btw, how do you run it in MAME with debugger ? make sure to use -nodrc switch, otherwise you may get wrong watchpoints/breakpoints/trace/etc results

@nem good work I would recommend few things: 1. as of digging info about how this 3D stuff works, it would be useful to look at Naomi SDK documentation and libraries, and maybe Dreamcast SDK 3D libraries (Ninja and Kamui) source code which is floating in the net 2. as of messing with game code -...

change netboot binary using this patch https://www.arcade-projects.com/threads/converting-gdrom-naomi-games-to-cart.1691/post-87668

@rtw worth to mention - smartctl.exe won't work with his reader until he added "-d ata" switch PS: one of dumped games, it took awhile to make it show something

much thanks! SPD PCB/ROMs are "Donkey Kong Jungle Fever / ドンキーコング　ジャングルフィーバー" medal machine. if you maybe curious what is it and how it looks like - search at Youtube for Japanese name, there is quite many videos with gameplay. MPV is boot loader ROMs from some CF-based game, not yet sure which...

huh, nope, I've said opposite, this one is dumped, it's mmaruchan set in MAME. your dump 100% match existing one, but thanks anyway

I wouldn't recommend to do that in this case. Medalusion games have some protection, CF data married with data from ATA IDENT reply, so, you have to dump both, and then optionally create chd image using chdman. this person already got toolset by rtw which we use in DU, with quite detailed...

hi here too :) I would say - there is nothing add to already been said in twitter. if there will be some specific question(s) you may ask me or someone else, like @rtw or @Darksoft as of WinImage photo with error: sadly, it's not something new, these Capcom CFs seems degrading withing time...

Triforce/Chihiro support doesn't exists in yours DIMM version 1.01, it was added in versions 3.xx idk if there also might be hardware issues. for sure DIMMs 1.xx converted to later versions works fine with Naomi, but IDK if it's true for Triforce/Chihiro too

have you read prev message ? in game proto you have to change country to US in other menu to make blood color option to appear yes. HoD2 proto doesn't care about BIOS at all, but set country, blood etc on it's own. you may use with it any of HoD2 BIOSes, doesn't matter which one, there will be...
