Henrik has tested the previously untested archive for Espgaluda.
There were 3 dumps within the archive and were from an unknown source.
Henrik says files U31 and U32 were working but U33 was not. Both these working ones are now added and the non working one is removed (although I will still keep it just in case).
Thanks the Henrik for testing
This chip is found in the Power Base Converter / Mega Adapter for the SEGA Megadrive.
Its a CK2605 but was dumped as a PLS153. I will get around to converting this to true PLS153 soon.
Today ive added the following
A GAL20V8 version of the Rainbow Islands B22-07. The version I originally made was for a 22V10. The 20V8 version was requested by IronGiant.
I have briefly tested this in my board and seems to be OK.
I also added a GAL20V8 from a Bellfruit Scorpion 4 PCB. Andrew96 was wanting to recreate this so together we have come up with this one. I am waiting for Andrew96 to test this but I believe it will work. I will update once its tested.
Andrew96 has sent in a PAL dump from his Screenplay board.
It was protected but he dumped it using the ABI Boardmaster and has tested it.
Thanks to Andrew96
Ive decided its time to make a start on the huge back log of repairs that I need to get finished.
Today Snow Bros was on the cards. It was a fairly recent purchase but as I really like the game it was first on my list.
Board boots up and passes its self tests but had big graphics problems.
Cant tell from the pictures but the screen is also flashing.
This board is tiny so I started looking for RAMs that weren’t program or sound related and shorting a couple of data lines together. There is a bank of 4 41464 RAM chips in the bottom left corner that would appear to be screen RAM.
First off I found the /OE on the left hand 2 were shorted to ground so I desoldered them. At some point a track had burnt out and was shorting against the ground pin above it. Removing this short gave me this
Much better, the colours are now sorted but the screen was still flashing and the graphics on the title screen left trails of the image. I checked the RAM chips I had removed and found a dead one.
I just went ahead and desoldered the other 2 RAM chips. Again, one was good and one was bad. I replaced these chips with an 81464 from a scrap board.
All working now. Ill have a game on this later.
