So I got handed an MT2 to convert to UC.

MAME file names don't line up with this ROM board. Anyone able to tell me which ROMs go in which locations?

Well, I figured out almost everything. The game plays proper, the backgrounds and title screen are good, and the sprites themselves are good but their palette seems off. And of course no sound (but that's because no decrypted sound roms yet).

RAM and ROM say OK on boot.

Between @ShootTheCore 's post on jumpers, and @8bitforlife double-checking for me I know those are correct.

I did search through the mame driver to see if "sprite" or "palette" pointed out where to check, but no luck.

EDIT: followed @psykom1 's thread, and swapped around 000 through 030 and got it MOSTLY right.

Not quite sure where to go from here.

I’ve converted MT2 to Undercover Cops Alpha Renewal without much trouble using decrypted sound ROMs from @Apocalypse. Here’s some tips from my notes:


Undercover Cops Conversion
34-37 require 27C080 or 27C801
(remember in MAME the files are inverted: 34 is actual 37, 35 is 36, 36 is 35, and 37 is 34)
23-26 and 9 require 27C040 or 27C4001
28 and 39 require 27C020 H0 and L0
27 and 38 require 27C010 H1 and L1
30 and 31 require 27C512 SL0 and SH0

Like @psykom1 I doubled up the H1 and L1 and set the jumper for it.

Aside from that I've ticked all the boxes in your notes.

This is where I'm at this morning.


And now:



Thanks to @caius repair logs I learned sprites are in 000 - > 030 which gave me an idea where to look. I'd noticed when the original roms were desoldered that the roms are wired in series (address line 1 of eprom 1 goes to address line 1 of eprom 2, etc) and took the multimeter to them. Pin 7 of 000 was not making contact with pin 7 of 010. Patched it with a wire and we're golden.

Thanks to caius, 8bitforlife, psykom1, twistedsymphony, brizzo, apocalypse, and shootthecore for getting me straight on this. Even if half of them did so unknowingly, ha.

Undercover Cops Alpha R was the title I was longing the most after to play.. but man did I get dissapointed.. :(
Its very nice and cool in the first 2 levels, but after a couple of levels it get very dull imo.. and the last stage is just long, repetetive and booring.. ;(
I really wanted to like that game... next ill try hook or in the hunt. Or maybe give ninja batman baseball a go? looks wierd but might be good :)

Unfortunately, I came to the same conclusion. I feel like the first two levels got extra polish that the later levels lack.

Definitely give Ninja Baseball Batman a try.

Hy guys. Not sure where to post this but I have a question about the 5v power needed for the m92 games. For example my mystic riders conversion runs under 5v. The recent undercover cops alpha needs around 5.3v in order not to reset. Both mainboards are recapped. And my original baseball Batman also runs without any problems below 5v. Does anyone know what this issue is related too? I also noticed that the higher I have to go with voltage the more washed out and out of focus the picture becomes.
Thanks.

Hi.

Can I get M-107 Fire barrel decrypted sound roms?

I have Air Assault decrypted sound roms, but I think it's not correct roms to convert fire barrel.

The game stops with some sounds effects.

I think it is why sounds roms are not matched with program roms(Japan version).

And I cant boot fire barrel pcb without sounds roms.
When I boot Fire Barrel(conversion) with blank socket of SL0 SH0, it dosn't work.

I need your help, friends. :)
Somebody can give me Fire Barrel M-107 decrypted roms?

Thank you!

@playero that Xevious themed bartop is amazing! CRT in it too? Looks really nice. 👍

Thanks!. 14" CRT is in it. :)

I made it with friend in my country. :)

I can change Control Pannels to play rotary-lever games, 2 joystic games... etc.
