I'm trying to repair a Golden Axe bootleg which appears to be the "encrypted bootleg" version (I've checked couple of EPROMs with romident). Everything is OK except the audio is trash. Checked the sound cpu ROMs and z80 which turned out to be OK. I suspect the PAL near the Z80 (sound section)...

Hey guys, I finally finished my side project. :D It took 8 months and every part, even the screws, have been restored/cleaned/rebuilt, playfield touched up and clear coated etc. This was my first pinball restoration... It was basically a junk before... ... and after 8 months of total...

As the title says... I've repaired another Sunset and the culprit was one of the mask roms. So it is replaced by a 27c400 anyway. Then I thought, should I go all the way :) I have another Sunset (repaired and kept) already installed in a cabinet. What should I do with this? Should I just...

Hello everyone, I know there are plenty of repair logs out there related to this highly sought after arcade classic Ghosts'n Goblins, either original or bootleg. But I decided to write my own experience with my recently purchased GnG PCB repair since I couldn't find a repair log specifically...

Remember the Street Fighter II: World Warrior PCB I mentioned about last week? Turns out to be my other WW had issues more than just wrong dip switch settings. :( Anyway, I ended up having no working WW PCB :) and I decided to fix the first WW which I shelved as spare parts. I've...

I've got this PCB from ebay cheap as non-working. I used to own an Aliens PCB but sold with rest of my Konami PCB collection (Sunset, TMNT etc) to support other projects couple of years ago. That said, I've been trying to put back together my Konami PCB collection again. Apart from...

As the title says. Is it possible to convert (or should I say - upgrade) Street Fighter EX2 to EX2 Plus?

Hey guys, I'm trying to repair a Naomi game cartridge for my friend. We only get a black screen when cart is inserted. One of the LCX16373 chips (16 bit latch) was getting extremely hot I replaced it. Still no joy. Checked the EPROM, it didn't checked with romident so I re-programmed it. Still...

Got some spare time and wanted to share my small repair adventure hoping that might save someone else's butt sometime :) Acquired this NSS cabinet in this excellent condition last summer. Getting this cab in my home arcade required a 1000 Km road adventure but that's a totally different story...

Hey guys, Just wanted to hear your opinions about this... Bought this PCB as not working. Was not booting at all. Repaired the A board (bent pins), replaced 4-5 sockets on B board (corrosion), burned a new STF29 PAL, reflowed the C board PPU. This was the best I could do for this repair...

I've bought this board knowing it has issues with sprites. According to the seller the sprites were missing. I've fixed the missing sprite issue. It was actually a sprite - background priority issue (sprites were drawn "behind" the background tiles) and the culprit was a physical damage on one...

I just acquired a CPS1 boardset. The seller was selling it as C & D. I knew it was a bootleg but the price was OK for just a working A board, a spare C board and sh** load of EPROMs. The B board is a genuine bootleg, not a convert/hack, with a PIC16C55 microcontroller on it. It plays the C&D...

Hey guys, Recently I was working on a rare (at least for me) arcade board and wanted to share my experiences with it; Sega Mega-Tech. First let me tell you the background story of this... How I got this PCB is rather a sad story. The local ex-operator found this Sega Mega-Tech arcade cabinet...

Hello everyone, I've been trying to repair a Sega Mega-Tech PCB. I've come to a conclusion that the "Mega Drive/Genesis" part of the PCB is not working. What I've done so far; - Board was not booting initially. - Replaced the SONY port expander chips (CXD1095Q) - they were getting extremely...

This is a non-corroded B board (Dungeons & Dragons: SOM - Japan). First problem was completely garbage screen but the sound, music was OK and game was blindly playable. I've checked the gfx ROMs with oscilloscope and found that the address lines of all the first column of gfx ROMs (i.e...

I received my ST-V multi last week. I was so excited, unpacked it, burned an SD card, adjusted the dip switches and plugged the multi into my spare ST-V mobo. Hurray! What a great product, thanks Darksoft for letting us play our favorite ST-V games on the real hardware... After some testing...

Hey guys, What might be the cause of the "EEPROM check" on ST-V shows up BAD? Changed the BIOS, cleaned the socket, still shows BAD. The boards boots up fine though...

As part of my preparations for my new CPS2-multi I decided to take care of the fan noise of my A board. I've replaced a few A-board fans with new ones which stopped the noise but I ran out of stock so I decided to solve this problem with guerilla tactics... ;) Then I found an old PC fan...

I know there are various scattered tutorials and videos scattered around the internet regarding this subject. I recently needed to install this switch in my Neo Geo cabinet and I wanted to put every mod in writing while I'm doing this so that anyone can benefit as a single point of reference...

Hey guys, I've bought a CPS2 multi kit from someone I know from KLOV which will be on my bench pretty soon. I'm super excited about it :) However I cannot decide which CPS2 to convert to a multi :/ I would like to hear your opinions about it... Now, I have these CPS2s in my collection; 1)...
