Hello!
I have decided to put the English translation of Akumajo Densetsu on my real cart and I followed the tutorial here .
I had no problems removing the old mask roms and soldering the new eproms.
I have triple-verified the 2 eproms: AMD 27C010 -120DC and TMS JL 27C020-15
The problem I have is that after an initial ~30mins gameplay the screen just went black. Reseting did not help , I had to remove the cartridge and insert it after a while. Then it booted again for ~10 seconds then it went to black screen again... the longer you leave it outside the longer you might use it , a classic symptom I guess.
Nothing burned and the famicom works fine. And the cart works for a while provided you leave it alone...
I have no idea why this happens, could it be that my eproms are crap? Already made a Gargoyle's Quest II translation cart with the 27C010 eproms, it runs perfect (used this tutorial here )
Here are some pics of my work on the cart, there are no burned traces or anything suspicious
mask roms removed:
eprom work:
and the back with the eproms soldered:
and here it is working for the little time it does:
Any ideas of what to check? Any help is welcome, thanks in advance!
