    WTB: Rad Mobile Deluxe PCBs or any other System 32 PCBs

    Bro I assume I could also need your Romboard. Mine has damage. But unfortunately I wasn't able to test if mine is good without a proper Mainboard. In what condition is yours? I think it would be good to have a spare one in stock.

    WTB: Rad Mobile Deluxe PCBs or any other System 32 PCBs

    Still searching. Alternatively I am looking for someone who could enable Drive Board Emulation in mame for System32 so I could use mamehooker.

    Can you swap Sega MPR Roms with Eproms?

    Any advice on those? mpr 13522,13521,13520,13519 According to the mame romset they are 512kb in size. I have a couple of M27C2001 laying around. As I understand they are 256kb, so they won't help.

    Repair Log: Capcom Vs. SNK Cart

    Hey folks, just wanna log this and need some help. I'll add pics later! I recently had this cart in the mail and when I fire it up it boots fine and even displays the license text and everything. After that the screen stays black and the game freezes in black screen. Rom Board test shows that...

    Can you swap Sega MPR Roms with Eproms?

    Okay, I've recapped the board and it turns on but of course there is totally garbled shit on screen with absolutely no sound and I cannot see anything, so I of course also cannot access the test menu. I tried to read the eproms and not a single one of them was read properly. Either it wasn't...

    Yeah! Please get a psu with adjustable voltages and make sure you have 3.30v and not more than 5.10v. Especially the Naomi's fairchild buffers and those of the games are prone to suffer vom overvoltage and will break from this causing the system all kinds of weird behaviour. One of my naomi 2s...

    Ha, told you. Got no thermometer as well but it immediately got hot when u turned it on. Maybe the cap is the issue. I got my Naomi's in the cabs and I am too lazy too take em out and disassemble them. Maybe I'll do it this week. I haven't found any schematics mate, sorry. As long as you won't...

    If it immediately after turning on gets hot, it's definitely toast. Replaced 3 of them in the last few months and it was always the same. Any idea where some can source the chips? You're welcome alex!

    Touch the 315-6145 and tell us if it's hot. According to your description it sound very much like it has blown. I wouldn't bother with the other stuff before checking that. Sorry. That sounded meaner than it was meant to be. ;)

    Can you swap Sega MPR Roms with Eproms?

    Is there some sort of compatability chart? I have to clean the other mprs but just in case they are dead too. And do I need to pinswap or are they 1:1?

    Can you swap Sega MPR Roms with Eproms?

    Geez! Thank you for the quick response. It's MPR 13518,13513 and 13512. What Eprom can I use for this?

    Can you swap Sega MPR Roms with Eproms?

    Hey, as I just found out some Sega MPRs on my Rom Board have broken legs. Can I get the mame data for these and program some eproms with it? Never done this, hence the question! It's Rad Mobile on System 32.

    WTB: Rad Mobile Deluxe PCBs or any other System 32 PCBs

    Hi, as mentioned above. I now own one of these beasts but it was rat infested and the piss ate through most of the pcbs. Would be cool if any of you can offer me any of those. Although I think I can get the Drive Bd. pcb working again.

    Sega ST-V Board Repair *help*

    Nevermind. I wanted to resolder the SH2 chips with my iron and of course the new solder I have is leadfree and I didn't realise that. Of course I made bridges which I am not able to remove, even with the IC desoldered with hot air. I read that the EU managed to ban solder with lead from private...

    Sega ST-V Board Repair *help*

    I probed the shit outta it today and spent ages reading the saturn schematics and making my own notes. I can trace all of the biosses pins back to the ls245's which are IC 3,4,5,6,7. So the address lines here aren't the problem. Any suggestions? If I don't get any I'll try resoldering the SH2...

    Mine with dead ramdac looked almost the same on 15khz setting. Replacing it made it fully working again. Is there sound?
