Yeah i think now best thing to do is try the romboard on a known good main board.
Send a pic of your mainboard too! Maybe it's a missmatch...

I also have this arena toshiden 2 according to the sticker on the top board , but the EPROMs read as street fighter ex so I guess someone converted it with those flash chips? The top board with the socket empty has that bigger Actel chip going there (have it laying beside it)

Yep that looks correct!
Does IC353 say -54 on the chip?
Yeah that's a bootleg conversion , would of been a toshinden originally.
Is this one also non-working?
Probably a good candidate for bios board
The 2nd VRAM is clearly added on too

-54 beastorizer gives me a blue screen but no code, with the bootleg top it gives me a code
Bootleg bottom board just boots to black without a top board

COH1002C is not compatible with capcom games.
I think the motherboard is fine here, but there's a top board fault
i think the black screen bottom board will have other issues
The top board maybe alright ...
.....
Swap IC's 652 and 353 from the capcom motherboard onto the raizing board
Then try the capcom top board with it... Probably it will run...
(put the DIP chip in socket)
If not, remove them chip carriers and burn all the roms with 322's from the mame set and try again
If not, i could do a "lame patch" so you can remove that actel thingy
----
This should leave you with the faulty raizing top board and faulty motherboard (and a couple of loose chips)
I would not do any more to the raizing top board for now, best to wait until i have tested the mach dumps.
Debugging the motherboard, usually looking for bad solder joints, scratches etc to start with

Brave Blade possible to mount on spare Bloody Roar 2 romboard? Or is Yamaha-protected?

I got Brave Blade running on one of Hammy's generic TPS322 rom boards.

Sound included?

only FX, no music :[

Yeah, I suposed that. I have a spare Bloody Roar 2 and I want to convert it to Brave Blade, because it's the same romboard. The only difference is Yamaha-DAC section (after converting to it some of the components have to be changed). That's why I am asking
Hammy

It's not worth converting these, Raizing blanks with the sound section won't be far away.
I will probably do a little 3 in 1 top board with BR1, BR2 and BB
The original is very unreliable.
I need to get hold of the atlus top board, and the NBA / Dredd top boards to see what's going on with them too.
If anyone has any of those three going spare, working or not... let me know
The taito stuff is another kettle of fish, it's better to run those on G net , or without sound, The taito top boards are nothing but trouble.

I have a fighter's impact. What can I do with it?

Keep it as-is, these custom top boards are not with messing with!
Just because i did it as a proof of concept, does not make it a good idea... It's messy

Spicyjpg has ported OPENBIOS to ZN1 :o
So now homebrew / PS1 porting is possible!
https://github.com/grumpycoders/pcs...nges/3e6bf9845be84f10b56e1ea5e2b27d4d1666f2b6
I tested it, and it Works great!
https://drive.google.com/file/d/1B1KilYPx1CZ6zw0wTBOf3U5qDIYcO1wT/view?usp=drive_link
So, if anyone has bios boards, you can now load PSX.EXE's from rom (providing they fit in the remaining space of the 512k/(4mbit) bios bank)
The EXE needs to be compiled into the binary.
Stuff needs testing and there's 1000's of things on PSX so give it a go with some random demo's / small games if you can
<expect crashes if the software you are testing may use CD commands etc>
The openbios is running on K573 hardware too, for those who missed it!

- BOARD=system573 will build a kernel that can run on the Konami System 573 arcade board. This option is only useful alongside EMBED_PSEXE, as it will force BOOT=rom and BOOT_MODE=psexe; as with Konami's BIOS, game booting is not implemented in the kernel and must be handled by a custom shell.
- BOARD=zn will build a kernel that can run on the Sony ZN-1 arcade board (ZN-2 support is currently broken and needs further testing). This option is only useful alongside EMBED_PSEXE, as it will force BOOT=rom and BOOT_MODE=psexe; unlike the official ZN BIOSes, OpenBIOS does not implement game decryption and booting in the kernel.
