Elgen has dumped 3 more PALs from Wizard Fire.
As with the other one these are untested due to the board being a non worker.

Thanks to Elgen

A few days ago my good friend Elgen took his first step into the crazy world of PAL dumping. His first submission comes in the form of a PAL from Wizard Fire. Its from a non working board so this isnt tested. There are also a few other PALs on this board but he believes the VA-00 PAL is defective.
Hopefully this marks the beginning of many more from Elgen.

Next up, reliable caius has sent in 3 PAL dumps from a Taito game called Fighting Hawk. Never heard of this one before but here is a complete set from that board.
Thanks as always to caius.

MrDo has dumped, tested and sent in a JED file for this Donkey Kong Jr bootleg.
I noticed that there is already a file in the archive for a bootleg and they are very similar in operation but there is a couple of differences so it is now added.

Thanks very much to MrDo for this.

Thanks caius

I’m on a roll at the moment and this one was one of the smoothest repairs Ive ever done.
Here I have a couple of boards from muddymusic. First up is Bionic Commando.

There was a ribbon cable missing completely. Ive got loads of these spare so that was pretty easy to replace.
Test time. The game booted to garbage.
First step was to check the program ROMs and found this on one chip

and this on another

With those sorted the game now boots although all the text is a bit messed up.

With the help of the MAME source which specifically identifies which ROM is responsible for text I pulled the ROM and read it. Each read gave a different CRC so it failed its verification.
Burning a new EPROM for TS-08 brought back all the text.

Job done.
