Does anyone know of compatible part number to replace the optical sensors in a Happ P360? I have two of them with bad directions and I'm trying to source a replacement. I may end up having to just crack open various ball mice to try and find some good pairs.

If this ever gets worked on again I just got my two blasts setup with VS marquees, so I'd be in for a set

the row that's checking bad is the SOJ RAM near the top left of the board (bottom left in the OP's picture) I don't like those jumper wires near that area either lol. e: Oh I see there's more on the bottom too, I'd stay away from this board unless it's ungodly cheap and you want to fix a lot of...

Oh good to know! Thanks

I used M27C4001s and swapped IC7 and IC2 for Psychic Force EX, haven't tried Fighters' Impact yet I used the 2.0J version of the MAME rom, there's a chance my 4001s might be counterfeit? But they burned fine.

I'd like to downgrade my Fighters Impact A to plain Fighters Impact, and my Psychic Force to Psychic Force EX, tried just burning the new revision roms for PFEX and it will boot loop to a green screen, assuming there's protection chips at play here?

I was sent donors for cart conversions and I received basically two carts stacked on each other, the top one being World Series 99 with no IC22 and the bottom cart is Dynamite Baseball with IC22. Dumped the IC22 and it has both games on it. I'm wondering if this was some kind of 2-in-1 that...

is that an original maxwell battery or do they still sell ER3s in that design? If it's an original, I'd recommend changing it..

Nah, it's an F Pal game and it works fine, I just had to move my graphic eproms

I'm super rusty coming back to this stuff, converting a Rev 7 board to Puzzle Fighter, has an F Pal, but when it's plugged in I only get game audio, if I remove the PAL the graphics return. I didn't have any M27C322 on hand so I was using M27C160 for 11 and 12, M27C800 for 14, 16, 18, 20. Game...

Well I reprogrammed my U13 with a M27C1001 and it just werks? For some reason there was an M27C2001 in there, probably what came on the game originally, I doubt I doubled up the bin when programming it. I've still had it error when starting a credit once but it boots every time now, that's good...

Actually reseating the eprom worked, but also reset itself again. I wonder if the socket itself is just making poor contact with the eprom, at least I know where the problem area is now, thanks! E: actually after reseating it it's resetting way more weird I may just replace the socket and also...

Hmm I wonder if it's conversion related then

It does a hardware check at boot, I'll sometimes get an error message to come up with debug stuff when I start a credit, but I'm never ready to take a picture of it when it does haha. I'm not sure if there's just cracked solder from board flexing or if my MAME rom conversion I did was not the...

Hey I have Jackie Chan I converted to Fists of Fire that will sometimes boot loop with a Check G errors or will occasionally error out mid game. I'm revisiting this now since I'd like to bring my board to Evo but not if it's going to be this inconsistent. Does anyone know what Check G is...

It DID end up being the bios on my 9600SE. I got it booting after burning the uploaded 9600SE bios posted earlier in the thread, now TGM3 boots right up. I didn't brick my GPU, I think maybe some alcohol was causing a short or something and it flashed off overnight. All good now. Thanks for the...

Looks like my Capcom i/o works, not my newer Taito JVS I/O (K9101262B). TGM still errors out for me. But seems like everything that had JVS errors beforehand, works fine now. I don't really mind the taito i/o not working since I just got this for TGM3 which I want to play on my blast. Here is...

Weird, I'll leave it on over night. Hoping it's just the game data being at fault. e: The games boot now, but I'm still getting JVS errors, and I think TGM3 has some memory error (0x000000000). I can control the game selector with my JVS i/o so I'm not sure why.

no one seeding games haha

I'm having some issues with my Type X, TGM/Chaos Breaker won't launch from the launcher, KOF98 errors out. If I try to manually boot TGM/Chaos Breaker, I can get some OPENGL32 error, if I manually boot KOF98 I get a JVS error. Input works on the launcher though so I think my JVS card is good...
