Solved Jack rabbit ROM dump needed (repair log)

[Georgian2]

Hello,

One of the CPU ROMS (TMS2764) is damaged and always gives me a different checksum on every read.
The romset that is available on the internet might be for smaller roms (2732) where mine hase 2764. See the mame code attached.

Dose anybody knows wehre I can find the ROM_LOAD( "cpu-01-4.1d", 0x3000, 0x1000) CRC(8e7fbbb3) SHA1(3d57ddf6a47d5f28e4fd24002e948287803a2438) ) file? Maybe you have a board with this roms and can dump it? many Thanks!

I figured it out. the 4l and 4h should be compined. 4l in the lower side and 4h in the upper side. It matches the 1B with 2l and 2h.

The watchdog still trigger every now and then... And I thought this will be an easy fix.

New CPU and it is working. Easy fix....
I hope the sound and controls will work too.
