[Naomi netboot] Melty Blood Actress Again won't start

Post by Mokum » July 16th, 2016, 4:21 pm

I've tried almost every single game and they all work flawlessly but when I launch this game the Raspberry gives me the usual "sending file..." message, then the Naomi reboots, it starts checking the memory and then, lastly, it loads the game.
I mean, it's the same process as every other game... but in this case, instead of the game, I just get a black screen. I tried waiting a little bit... then a bit more... then a lot more... nothing...
I read somewhere that the netdimm got to be a 512 Mb one and it is! I ran a memory test: everything's fine... I tried downloading the game again: still no changes at all...
I don't get it...

Think you will get the game to load like other games then get a message of "memory is not enough" if you don't have enough ram

This is why I wrote I've got a 512 Mb net dimm...

Also, the game "loads" forever but I always get a completely black screen, no error messages at all...

I can try sending you a new .bin that I know works. I won't be at my PC for a day or two but you can MP me if nobody else helps you out.

I tried Senko no Ronde New Ver (requires a 512 Mb net dimm) and it works just fine so no, it's not a matter of memory...

Do you have a coin meter on your cab?
had some games not work unless it finds one
not sure if this game is one of those or not

Will have a look at that because I tried the file skate323k137 sent me and it still won't start :(

I tried it and get the same result (black screen). I did spoof the coin meter on a Sega JVS IO v2 though.

What is your bios version? You need an H bios, this game will not boot on any older bios, even if most games netboot on them. For example a G bios will boot most games but not MBAA.

I have a H bios, actually I'm using a multibios right now.

How do I check the version?

I've found this post:
p1pkin wrote:latest ones, rev C Naomi2 and rev H Naomi
But how can I be 100% sure mine is based on the same? Maybe because there's only one multibios out there?

Yeah the multi's are based on the latest versions (H/C)

I don't know if I've ever booted this game on the multi bios, but anyway, I also sent Sp33dFr34k the .bin that I know works on a stock H bios. Hopefully he can get to the bottom of this.

Worst case I can also test with a stock H bios and multi bios at some point.

Ok, so skate323k137 sent me the .bin he's using for this game and I've tested it, my findings are:

- Japanese H bios: works
- Modbios: works (USA setting)
- Multibios: works (Export setting)

I also have a 512 MB net dimm and have no physical coin meter connected, I spoofed it using a Sega JVS IO v2.

However, I think I found the issue though. The script I was using (I'm using the piforcetools in combination with the web booter) was pointing to this image:

MeltyBloodActressAgain_v6.bin

That was the image which did not work, not sure why. Maybe you have the same "problem". You could alter the script with the roms or simply delete the MeltyBloodActressAgain_v6.bin file and replace it with the file skate323k137 has. Don't forget to rename it back to MeltyBloodActressAgain_v6.bin once you upload it to your rPi.

Let me know if it works for you then.

Nice, that sounds about right. I also have a copy of that "v6" bin that has never worked for me.

Cheers fellas.

Nice findings!

I'll try booting it with the multibios set on either USA or Export.
If this won't work I'll delete the _v6.bin file and rename the file skate323k137 sent me so the rPi will boot the newer file.
I'll keep you updated!
Thanks!

BTW the _v6.bin one is the "patched" version, while the other one is the "non-patched" version of the same game.

No clue what this means though.
