Hi,
Sorry about the noob question.
I have a Double Dragon bootleg that has graphical glitches (some vertical lines in certain sprites/tiles, sometimes on/off).
I would like to at least confirm that the EPROM's checksum concur, but I can't seem to be able to read part of the EPROMs.
This is the board : https://edgeemu.net/details-8248.htm
I can read the 27C256 on the board, but not the 27512, at all, I get FF's everywhere. If I read them as 27C256 I get data, and corresponds to the second half of the bank of the ROMs from the mame archive.
I have a Xeltek Superpro 500P, that is very versatile but not with this.
Thanks anyone in advance.
