Double Dragon Fix

[grobda]

Got a Double Dragon with garbled background graphics;

I consulted the mame source to get the locations of the background tile eproms which tested ok. Schematics showed background RAM was at IC57, so after testing most of the surrounding logic with a probe I piggybacked a TMM2018 on it and got this;

Better, so I replaced the RAM, and bingo;

Chucked a few credits in it and played through the game. Last time I did that was in Southport in the late eighties, when I begged my mum to let me finish it before we went home. I remember it costing 60p to finish but my brother reckons I spent a quid. He dropped out after 30p.

Awesome, Always like to see a double drag brought back to life

Those toshiba rams run pretty damn warm on those boards

One of my favourite games,betwen at Google Play have Trilogy and the original music is mixed and sound very nice.
Nice fix.

good work, sir.

i'm glad double dragon is still an affordable game so people can enjoy it!

(still wished it'd cost £40-£50 though) =)

Looks like the same thing that I get with my DD bootleg board


You fancy having a poke at it?

Looks a bit different with the lack of sprites in that video.

I've tried to fix other peoples stuff in the past but it doesn't always work out and can get frustrating and time consuming for both parties, so tend to stick to my own stuff - some of which has stayed unfixed for more than a decade.

I'm a closet DD fan, can complete without losing a bar of life.

A bit late to this thread, but: could these problems be RAM related, anybody...?
