I had in my console xtender v1.1 in a W29C020(Eraseable), then i decided to get Evolution-X v2.6 in a AT27C020(OTP) without any result.
When i replace the xtender for new evox 2.6 the console wont START, then i put back the xtender and console works.
After it, i got a backup of the file present in W29C020 and I made a AT27C020 with this file, but THE SAME, the console wont start. The only way to make console work is use the W29C020 memory with Xtender v1.1
When i try to transfer code of Evolution v2.6 to W29C020 it wont program the memory, appear an error like, CANT PROGRAM 13 SECTOR, VERIFY HARDWARE or FLASH/EPROM, when i put xtender code, it works.
Im using to make the chips the batronix EEprom Programmer v3.3 with Prog-Studio v5.13
I hope somebody can help me!
