Ah, then in that case, GAL chips need to be swapped too (are they dumped?)

I did it years ago, but don't remember anything funky, except the 8 pin "settings" chip. No patching was needed, that's for sure. View: https://www.youtube.com/watch?v=mRnmBgq18Zk

I have not looked at the code for these, it also looks like the world version "life force 2" is in there too. I have not looked at salamander 2 yet, it uses a "different work ram format" ... Twinbee and sexy are the easiest to do, the newer games get more funky. Winning spike was different ...

Original on the right, cracked version on the left. Thanks to @nnap for the video View: https://youtu.be/Z-pamZ66dCk The only way to do this is with guesswork , it will be more or less impossible to make the snow identical if working at all.

It's a very long and complicated process, basically code needs to be re-written to build the sprite list and gather all the info from work ram. The best thing to compare it with, it's similar to porting CPS1 > CPS2 Sadly, the program to do the "snow effect" on sexy is not in any other game (the...

Got winning spike now fully de-protected, and sexy parodius at about 80% "cracking" most the games needs the sprite system re-written... However , i don't think the "snow" effect will be easy to do for level 1 (it's missing on mame too, there's no example code for it in other games.) When...

Yes, that's the "player station" board. I have dumped one already "Caribbean roulette" or something If you want to get the roms dumped, i am based in cheshire, you are welcome to drop by, or send the board / chips.

They will be back for sale at some point in the near future, but for the moment, i'm still not setup to build them.

This one needs to be dumped if you can do it?

I think there's a MCU also involved? (maybe a H8?) I can't remember for system 11.

Check the CPU socket

Don't need to delete my post, I don't mind being called out, because it's always wrong / a misunderstanding. He seems to think i have stolen his jank. Let me back myself at least? , anyway pics are there, he will collect them wednesday and this will be done and dusted. AFAIK being accused of a...

Come and get em'.

Did you dump your original roms? they may be another version that used another chip?...

yes, that's it! ... so do you think BBB only works with this stuff removed?

Hmm, have a look at your board that boxing boots, i'm pretty sure its about those 3x TTL's... I'll take a picture tomorrow to show you!

About the motherboards, i have one with the extra connector and TTL and it does not seem to run with boxing etc. Is this motherboard only for quiz / mahjong ?

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 View: https://www.youtube.com/watch?v=SUCJuw3f6Mg

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...

It should be possible to bypass the custom with a little board in the socket and just run decrypted.... It's on my to-do list... (along with blanks...)
