Hello Guys,

Using 2MB EEPROM i merged C1+C3 , C2+C4
I am using a CHA256 and a ProgTop even though the game originated on a CHA42 and PROG42.
The game starts and looks ok, but it's too early to be happy, as soon as I enter the game there seems to be graphical errors on the buildings. ?(
I seem to be getting the wrong sprites .

sure this is an error on the C roms, I take them apart and check the CRC again, and it is right.
So is it possible that it is a problem with how I am arranging the data ?
Maybe if I use the 27c800 the error disappears ? but I don't understand why it should.

On the definition of the rom on the mame there doesn't seem to be anything strange, maybe it's me who doesn't understand something.

ROM_LOAD16_BYTE( "016-c1.bin", 0x000000, 0x100000, CRC(71471c25) SHA1(bc8e3fee56b33ef2bac5b4b852339d2fbcd09b7c) ) /* Plane 0,1 */
ROM_LOAD16_BYTE( "016-c2.bin", 0x000001, 0x100000, CRC(320db048) SHA1(d6b43834de6f5442e23ca8fb26b3a36e96790d8d) ) /* Plane 2,3 */
ROM_LOAD16_BYTE( "016-c3.bin", 0x200000, 0x100000, CRC(98de7995) SHA1(e33edf4d36c82196d2b474e37be180a05976f558) ) /* Plane 0,1 */
ROM_LOAD16_BYTE( "016-c4.bin", 0x200001, 0x100000, CRC(070506e2) SHA1(3a2ec365e1d87a9c5ce1ee9bea88402a8eef4ed7) ) /* Plane 2,3 */

What do you think ? bets are accepted :D

Ok guys, i just fixed it right now with 4x 27c800.
Some one can explain why ? ?(
 
I am really interested in the answer to this post. I don't have much to help though.

I seem to remember a thread on AP with a completed reproduction MVS cart pcb. It may have been just the PROG board but I thought it was the CHA board as well. I searched and found this thead which does not appear to be finished:

Am I dreaming or did someone create this?
