just downing a cha now! with bootlegs there even worse than originals because the though holes are smaller also cheaper double sided pcb with thinner trace material so easy to go pear shape. you'll be up shit creek without a paddle in no time lol
The Midway boards are so bad, some of the bootlegs are better! Had pretty good luck with Bootlegs that don't run Galaxian (UniWarS or Moon Cresta for example), could desolder the chips quite easily. My trick is to heat the leg on the component side with a regular soldering gun while desoldering from the other side, this way I even get the chips out the Midway boards without ripping too many traces. Don't get me started about our Midway Galaxian having the chip legs bent over on the bottom.
@@senilyDeluxe With the correct techniques even removing a PGA CPU is pretty easy. I just fixed a bunch of Sega boards, these are 4-6 layers so just using powered desoldering tool won't get the job done.
Looks like 64H is missing from the sprite address decoding. (a bad data bit on one of the sprite RAMs would do the same thing) I got a genuine NAMCO Galaxian board someone had converted to Triple Draw Poker in 1984. It just HAD to be converted back to Galaxian, I bet the CPU was in pain running that crap card game. Worse, the palette ROM was different (with an inverted blue channel so you wouldn't get blue on a regular monitor). I didn't have any programmer to burn those 32 Byte PROMs, so I built one myself. We also have a NAMCO Galaxian hacked to play Knock Out (an Amidar ripoff). I left it, it's not that bad and we have enough Galaxian boards playing the real deal (or a bootleg thereof)
lol I hope this vid is flagged not for kids....firm breasts, 4-letters often etc lol The Galaxian fault is very easy to fix. First start by downloading the test program and run it and maybe it will just be a bad RAM. Otherwise it's going to just be a logic chip.. very easy to fix as pretty much everything is accessible on top. Try fixing a multi-board like Daytona or Time Crisis, can't do a damn thing as everything is plugged in on top of everything so much more challenging to fix. I could take a look if you're on the West coast.
Loved it!

Yeah, I'd noticed some of these midway boards are *incredibly* cheap. The VRAM/etc. daughterboards on MsPac are held down by zip ties...

you get some modern board data east in the 90's multi layers for sure
the infamous jujitsu tonka chipz! it could be..... on that pcb

Wth was that apology of alcoholism?
