I just had a look at the Namco Sys1 game list and found this obscure game called 超絶倫人ベラボーマン, Bravoman. It seems to run together with a custom I/O board for the buttons. Does anyone know anything about this?

Working on another Sanwa 1723c chassis, all caps have been replaced. This chassis horizontal position can't be fully adjusted, it's too much over to the left side (with some fold over on the right side). There are two hori-position pots on this chassis, one main pot at the front side of the...

I just got hold of an Afterburner upright arcade machine with Afterburner 2 in it. It seems that Sega were lazy when they developed this game, because when in Free-play mode (DIP switched) I still need to insert coin to actually be able to play the game. I found this site...

I have 3 working A-boards that I've collected through the years and as most of you know, the A-01 chip on these boards are notorious for going bad. Is there any way of extending the life of the chip? Would adding low profile heatsinks make them hold up longer?

I made a newbie mistake. I flipped the JAMMA harness connector on to the edgeconnector on my Thunderforce AC conversion and toasted som DAN803 diode circuits. I desoldered these (2 out of 4 that went bad) and replaced them with the non broken ones and now I have some stuck inputs. Namely the...

I've seen a semi-multi on the Namco Sys1 hardware, but it was one kit for vertical oriented games and one for horizontal. Has there been efforts in making a full multi kit?

Hi, I'm working on a Sanwa PM1723C which loses V-hold when it has been running about 20 minutes. It all starts out ok, but after 5-10 minutes the image start to twitch a bit. And after 15 minutes the image starts to roll vertically. After 20 minutes it rolls so fast that I cant distinguish any...

Hi, i have some old Konami games like Time Pilot 84 and Juno First that are oriented "incorrectly" in regards to more modern JAMMA games. One way to resolve this is to flip the yoke connectors, but I'm wondering if someone has thought about pathching the game ROMs instead? Like inject code that...

I have a Hyper Olympic that’s missing its custom 502. Are there any repros made of it or do I need to source another donor board?

I've gotten hold of a Taito Mexio 86 which is missing it's top board. Basically this is the same hardware as Kiki Kaikai is using, except for a MCU that differs (and maybe some PAL-chips). Has anyone tried converting this into a Kiki Kaikai?

Looking for a 74LS244 SMD IC to repair a JK-03 hybrid for a Jaleco Mega System 1 board.

I'm working on a P-47 that has faulty sprites. the graphics are missing. I found this video which shows a RAM test function in P-47, but is it in the original ROM?

I'm working on a Asteroids Deluxe pcb which seems to have a bad Atari POKEY chip C012294-01. I would like to get hold of a replacement Thanks

Hi, I have a Namco System 2 board that has some weird graphical issues and the fault is due to a faulty cpu board. Does anyone have a Final Lap 1 or 2 that you can part with? :)

I've seen that BEEP Shop in Tokyo has figured out a way to revive their dead Konami Bubble System boards. Has anyone of you heard anything besides these snippets from Twitter? :)

EDIT I've found a kit :) Send me a PM if you have it for sale please :)

I was thinking about the old Major Title to R-type and R-type 2 conversions. The R-type 2 conversion is pretty clean, no extra wires and such. But the R-type conversion is pretty messy. Extra TTLs and RAM and alot of wiring. Can this conversion be cleaner with a patched PAL? And yes, I'm...

Hi guys, I’ve been working on some Namco System 1 boards and also Pac-Land and on one of the boards, the 40-pon custom 27 is not working. This acts both as a clock divider and as sync genratoe. Is it possible to reverse engineer this into a new DIP 40 chip? :) I’ve seen JROKs page about his...
