What do I need to convert a TEKKEN 2 VER.B back into VER.A?

[Franco23444]

Hello! As the title suggests, I want to convert a Tekken 2 Ver.B PCB back into Ver. A to complete my Tekken collection. I want to know what ROMs I need to swap out to do the conversion? Any advice is greatly appreciated! Thank you!

Here you can find which roms are related to each revision: https://github.com/mamedev/mame/blob/master/src/mame/namco/namcos11.cpp

No matter which version you choose to convert to, all share the same "bankedroms" (the rom pcb), samples and sound roms. The only ones that differ between versions are the program "maincpu" ones, which are the group of 4 Intel flash roms on the motherboard (2L 2K 2J 2F)

 

[twistedsymphony]

if you're good at SMD rework, and have the right flash-rom programmer and adapter.
1. desolder the program Flash ROMs,
2. re-porgram them in your programmer/adapter
3. resolder the program Flash ROMs

there are a few threads on this process already:

Thread 'Found Undamped Namco Tekken 2 ROMs ?'

Dec 3, 2023

Hi guys
i recently aquired a tekken 2 pcb with a sticker saying its a "TES2 - VER D" i tried to check the Program ROMs (2L, 2J, 2K, 2F)
i dumped 2L and used romident website and nothing was found about it !
now i am confused, i don't know if the rom i found is corrupt or if its undumped rom
the board says its a TES2 VER.D and i found no such version !?
any help will be appreciated
thank you

alternatively you could build a custom adapter that allows re-flashing on the PCB by way of the CPU board connector. Theoretically possible though I've never seen anyone attempt it.

Neat! I saw someone selling a Tekken 2 PCB near me and will definitely pick it up to convert it when I get the chance!
