I have both 260 and 210 in 1 (and they will be dumped by CaH4e3 some time later this year), on mine the PCB have less TTL chips. I think mine are original releases?

It can't be mapper 235, because it can also support one UNROM game (which is programmed into smalles 128 kB DIP28 mask rom). I have few questions about connecions, can you answer them?

Does the hardware work that after one reset - this menu with 200 games is shown, and on another reset - one UNROM game is loaded?

Ok, so I am almost sure that this is 100% rev-en pcb:

Weird thing is that when horizontal mirroring is set, CHR-RAM is write protected.

It depends how you implement the reset switch in emulator. 2048+128 is more logical.
