Repairing a Raiden bootleg

[16bitgium]

Hi guys,
In my pile of broken and unknown PCB's . I found a bootleg Raiden. Suprisingly it works ! There is however one eeprom which has been abused. I think it is the rom which stores the background graphics because when I wiggle it a bit I get no background image.

So I would like to make a new rom chip to replace the very dodgy one: It is a 27C512-25. I see extreme price differences what are the best to buy and where (in europe preferably). Which type of rom burner do I need to get (preferably one I can use for other projects in the future.
It seems I have a Korean bootleg I assume it is this one:

I count 22 eproms on my bootleg Motherboard however i see only 14 files in the rom file. How do I discover wich on is the correct one ?

Thanks in advance for your tips!

• to know which one you have: you dump a rom and your rom ident it
• cheap burner to see if you like it: the "TL866II Plus"
• You'll also need a "eprom uv eraser"

both of "these" can be found on ali express.

You could always desolder the socket from the bottom and attempt to dump it from the socket

This bootleg is very common, i'm sure it's dumped??
Anyways= I'm sure it can be figured out by dumping the other 3 and looking how the data is split.
