Hi. I want to share an improvement I have discovered after studying the 2 versions of The Newzealand Story sets. When I plugged my new set board, I noticed the sound was really bad comparing with the sound of old set board. The midi sound effects (arrows, bombs, impacts, jumps...) were really...

I have collected a Ninja Kids single board version, but have a little glitch when presenting the sprites. In my opinion is a problem of drawing priority. In the next image, you can see part of the scroll is "devoured" by a part of the window, and also the white background of Hanzo. In the...

Bought a working Kick'n Run Taito jamma board. Many thanks again for this purchase to @Lady Bug. In UKVAC forums I made another purchase a year and a half ago of 3 Taito Cup Finals boards, and very glad. Soon we are going to make another one, xD.

Hi. Soon I'm going to have my own TZNS single board game, and I have the doubt if the infamous M-CHIP (B53-09) can be replaced/avoided in the original board if it breaks. In MAME says it's a i8042/i8742 with internal rom, but I don't know anything more about it.

Hi. Searching for a Kick'n Run board, working or not. Shipping to Spain

In this tutorial I'm going to show how to do this conversion. For this game to be made, you'll need any donor except Avengers in Galactic Storm. Open the board using the 2 plastic pieces of the sides. Be careful. If you find any screw below the case here, quit it. Of the 2 boards inside...

I sell 2 units of Cyvern converts (japan version on blue shell) I personally made. They include an specific modified BIOS for making them work in any Supernova motherboard (mainboard region doesn't matter for making them work). They are inside ROM-BOARD that I upgraded to ROM-2-BOARD for making...

@Darksoft Hi. I have just discovered a solution for a mysterious issue with installing old multis on 93646B-3 boards. The problem is, after updating the bootloader with STM32 and flashing the new image update via SD, the code injection of the games doesn't work even using good quality cables and...

Hi. I upload here a not accepted version of Wild Fang by MAME team. A year ago around this date, I dumped a board that came to my hands, and sent the binaries for them to be studied. These binaries were classifed as a hack, not sure why, they didn't gave me any reason. They only saw that "too...

Hi. I have made a provisional schematic of how I think P2 rom latching works on Vortex cartridges with games higher than 1MB+4MB total CPU size, targeted to PROGBK1 original boards. The idea is to add a new LS74 for latching D2 signal, which can improve P2 from 4MB to 8MB using the same logic...

Hi. I search that Taito B system board

Hi. I have tried to repair my original Fighting Layer unit. I have exchanged working mainboards (checking and transferring all the necessary roms, even reading the ones in romboard), and it seems the MACH211 KC037 KEYCUS is broken. So the only solution for repairing this unit is hacking it, but...

Hi. I have tried this little experiment for flashing this damn type of flash memory. As 26L6420 is so special, I imagined it could be burnt as 2 x 29L3211 mode, by tying A21 pin to GND and +3'3V (for accessing to low and high half), changing WE 26L6420 signal to the position of this pin in WE...
