Sheep_nova's GAL logic uses A15 input signal of the P1 rom for activating the largest input signals. It's not worth to improve

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...

Solved, many thanks for the tips. After a few more time inspecting, I have discovered a self destructed trace hidden below a leg. This discovering is due to a extrange state in one of the LS157 in charge of A signal in the FRAMs. One of the LS157 input values seemed bad, so after using the...

So I could try to exchange WT2 of FRAM zone for another WT2 and see what happens, right?

Desoldered FRAMs and the 2x74LS245, all are good. Also the rams are being activated, so the error must be something deeper. What are "WT1" and "WT2" components?

I have forced error on other rams, and I obtain LRAM ERROR joining input signals in these rams: So almost for sure, FRAM ERROR must be these ones:

Hi. Does anyone know how to repair this issue? What do I have to check?

Any MVS fake converted game with yellow shiny case? I only want the case for making a convert. I don't want yellow cases from 161 in 1 cartridges-alike, those yellow cases aren't shiny. I want KOF 2002 and Matrimelee yellow case type.

Well, this is it. I have improved this "Violence Mode issue" on Light Bringer 2.2O definitely. I want to come again at this screenshot: In the EEPROM offsets 0x12 and 0x13, the values that are shown are: 02 01, on Dungeon Magic 2.1A, 2.1O and Light Bringer 2.1J 02 02, on Light Bringer 2.2O...

Well, I have good news about Light Bringer 2.2O english version with "Violence Mode: Hard". I have loaded Dungeon Magic 2.1O rom and Light Bringer 2.2O rom for seeing what is saved in the EEPROM files, and I have the following info. When loading both games, I have established eeprom on FACTORY...

The thing would be to unlock blood option on test mode in 2.2O, and with that we all would have Lightbringer in perfect english with blood option

Sold

Selling a complete game convert with mainboard. Convert made on ROM-2-BOARD original cartridge PCB. Fully working. 300€ + shipping from Spain.

Yes, it has. But I was trying to update it for using CF cards, but being this the NAMCO media board with only NAND support, I have to exit the room silently

I have a deep luck, damn, xD. Thanks

Hi @nem. I have a Triforce Type 3, sd revision. This motherboard doesn't have the 2 dipswitches you say. How can be put in netboot mode?

Found one

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.
