Well its working but totally unplayable. The next step would be to try it on another system but I doubt it will help since every other hucard works fine on mine. I suppose there is not much that could be done with a malfunction hucard since the PCB is enclosed.
The keyring is a neat idea, in retrospect some kind of lamination or varnish is propably required to keep the printing from rubbing off.
Yeah, just to further corroborate what Black_Tiger and soop already established: I was surprised, myself, because I had hundreds of TG-16/PCE HuCARDs over the years and for a long time I *never* encountered a Huey that didn't work after basic cleaning/repositioning card in slot.
But, when I got a glitchy PC Genjin 2 and several bad Arcade Cards (both types), suddenly I realized that it was a legitimate problem, though thankfully only a small (I hope!) number of HuCARDs actually fail.
Now, my PC Genjin 2 looks *perfect* and is in excellent condition.
But the crappy, beat up replacement Huey (seriously abused) works fine.
Submerged in water?
Entered a wormhole?
Exposed to Chernobyl?
Who knows?
FINAL: My card is identical to yours, it plays, but with glitched graphics. I tried to play it (since I know the game so well)... and I was able to get pretty far...but a normal human probably wouldn't make it all the way up the waterfall.
IF YOU ARE SILLY LIKE ME, AND WANT TO GET MONEY'S WORTH: It might be fun to try to see if either one of us can beat the first world or two. If you can run emulator as a guide...it would work.
I'm not joking.
Now, when I did this years ago (before YouTube existed), I had TG-16 w/Bonk's Revenge running at same time as PCE w/PCG2 two monitors side-by-side.
At the time, I was taking photos of the two screens with a camera (ha!) and the results were pretty good (considering my no-budget)...
Sadly, I lost a lot of silly things like this when old laptops + harddrives were lost to fire/flooding.
Local backups need to be in a safe place. I was dumb.
