Spotted one on YAJ with starting price of 100 yen: https://buyee.jp/item/yahoo/auction/o1137215645. Curious to see what price it will land on such a short auction time.

Hi, yes I'm still looking. Do you have price in mind or would you like me to make an offer? Also updated the first post on what I have found and how much I paid if it helps someone in the future.

Bought a Cats Mahjong game system from @system11 which arrived safely and well packaged. A great person to deal with and was really helpful to answer all my questions. Thank you!

Was directly inspired by @buffi design so I thought that this might be best place to post this but let me know if you want to keep this for the original adapter discussion only I can move this to own thread. Finally got myself control panel to play some mahjong games. I don't have room to use a...

I got the picture from the initial post that the seller had sold it as working (sound included) so I figured it might be something simple on the setup that people might overlook like the -5V requirement. It has certainly caught me off guard since not all my cabinets have it wired. Not familiar...

I don't have Silent Dragon but I have Crime City which according the System16 website is same hardware and it requires -5V set on from my Supergun for the sound to work. https://www.system16.com/hardware.php?id=660&page=1#1649 Have you checked that does your Supergun output -5V or do you hava a...

I think @caius made a RCDM-l1 repro a couple of years back but couldn't find them for sale. Might be worth to pm and ask if there is still stock left or how to make one yourself. https://twitter.com/caiusarcade/status/1120640324274139137

Thank you again. The 03 at 5261 (dfeveron) and 5280 (feversos) indeed did increase how many bombs you can use but game still shows only 3 bomb icons and it removes one from the screen even when there are more that they indicate but when the icons ran out it didn't stop from using the remaining...

Thank you for the great tip. Was able to get the debugger working and get it to stop when the memory was set to '3' for bombs but still have a lot to learn on how to use the tool effectively and understanding the output it gives. Will have to dive into some tutorials maybe next weekend or when...

Thanks :). I Like doing a little write ups on the stuff I have done as it will also help myself to retain the things I learned. I managed to spend some more hours partially trying some tips and trick on finding what to modify and some just trying to brute force stuff. Made some discoveries and...

Bought the Fever SOS pcb this spring and while the game is fun and addicting to play I'm not good enough yet to get on to the highscore table. By my estimate you would have to play really good to at least to 3rd boss to even get to the last place :). I stumbled onto Zakk's hack for the Dangun...

Game PCB: Battlantis Symptom: Game was constantly resetting on boot up. Some garbled image could be briefly seen before reset. Bought this game knowing it wasn't booting up but the board was really clean looking and the price was right so thought that I could do with a challenge. Started...

Game PCB: Tekken (1) Symptom: Blue color was missing I got a second Tekken in a bundle with Tekken 3 with knowing that it had the color issue. Figuring it would be an easy fix. Probing around the game with a multimeter when it was running the blue on JAMMA edge had close to zero voltage. So...

Game PCB: Fever SOS / Dangun Feveron Symptom: Settings were not saving and on some full power off and on boot ups a very specific settings were loaded Recently bought a Fever SOS board with Dangun Feveron ROMs installed. The game was sold without issues and but noticed that on some boots the...

I tried my hand on creating the CP with a Hammond box but couldn't find a perfect match for 14mm square buttons I was hoping for. Best one I could find was 1591XXFSBK which is around 22 x 15 x 5.8 cm (L x W x H) but with the 14mm buttons it just one button short to creating the commonly know...

Stumbled on to some decent looking kit and the price isn't too bad looking at the quality. Only thing holding me back from purchasing it is that the control panel looks a bit flimsy but I guess it would get the job done if you would play with just SuperGun. Wonder was this some mass produced...

Game PCB: Tekken (1) Symptom: Player 4 inputs (player 2 kicks) shorted to FF00 For background information I mostly used my SuperGun for testing and I have Tekken 2 (ver B) and Soul Edge (ver. 2) which do not have issues so I ruled out problems with the SuperGun and harness. Also tested with...

The Crude Buster was weird for sure since all of the ROMs look to be from factory that they haven't been replaced or anything. My best theory was that a friend of the seller pulled prank and forgot to tell them :). It is a decent game and fairly inexpensive. I got it for 50€ with the GFX issue...

Game PCB: Dark Seal Symptom: P1 movement were working but actions were not (Attack and Magic) Steps: Traced the malfunctioning controls to Data East resistor array looking chip RCDM-l105 The voltage drop when pushing buttons left it in around 3v. Futher inspection showed that the action...

Game PCB: Crude Buster / Two Crude Symptom: Bought this as with graphic glitches. Most of the graphics were working fine but a few sections had some weirdness. Steps: Checked the Mame rom files documentation that the top part of the board were the graphics (GFX) roms Started to check if...
