AES Palette RAM error fix?

- Start date
thanks, Xian Xi. i dont know what i would have done without you. really...
turns out, when i soldered one of the wires, it also was attached to one of the legs next to it.
as i sayd before, my soldering skills where not good enough
i was having blue, so i will fix this mess, or try to. if things are not solved that way, then i will move to the bios thread, for debugging this thing and so on..
thank god to this forum.

this is how i did it, hope it helps others. i used an old ATA cable, the one wich goes from disk drives to motherboard.
my blue screen starts having some weirds lines, but they dissapear quickly
and this is what happens with samurai shodown 2 in the machine
sometimes i swear i saw japan simbols
maybe i wish too much...
never had my own aes, so i dont know what to expect, this is why i wanted to show with pictures.
there is no sound whatsoever
the cartridge is freaking clean, looks like a new one.
and here this ends, until my empty ROM's come home, and i can burn on them the diagnostics and so on
unless you have any more suggestions, of course

i did check again my wiring, this time it was perfect. i can only assume the other side of the board has also damage at some point
while testing with my multimeter, i noticed the closest pins always dont beep, but it shows small resistance, not pretty sure to be honest i didnt study electronics..
so i only can guess, the other side of the board loses continuity as well at some point, and that gives me those readings?
what should i do... re-wire them to lspc2, or add new wires from repaired tracks to lspc2?

well, i just ended up removing my wires and re-wiring to theyr place according to schematics
i still have the same problem, but somehow i like more the output , the broken traces mentioned before have continuity again
so i probably didnt mess up this time
