I did check both Pitfall and Pitfall II, It's fact that Pitfall II does, if you stand on ladder above scorpion, the scorpion does stay at ladder, blocks and doing flip-flops like crazy..
I got it work by using DASM command, played this strange game... you are turtle, trying to avoid object throw by dino-type character. nothing special there.
Thanks.... but one of many prototypes don't run at all, scanline or vblank issues.
that's file called Video Cartridge Bicycle Trainer (Bike Trainer) (03-06-1985) (ExerVision, Leonard Dorfman) (Prototype) ~
I am using Stella 6.7
DA4K
Stella 6.7 detected wrong controller (paddle), I changed controller to Joystick, now playable.... move joystick right or left to drive, accelerate = press fire and hold, slow down or brake = release fire. Warning: it's not easy to control.... hope you can play..
your version of duet (now Pas De Deux) is better than Diamond Drop. Ported from Apple made Atari look like Apple 🤣 I am enjoying play this one, but impossible for me to get pass 4.. 😚
Sad to see what happen to VHZC stuff been destroyed by flooding.. In future to prevent them from happens again, He would have to upload his sources, codes, and games to his website, Google Drive, or where he want to upload to. 😉
Try play in Advanced mode to see if you get bug, Chris... To me, both A and B modes does not fails on this.
In Blocks, Advanced mode has 7 colors, while Beginner has 5 colors.
Sound like you are playing (A)dvanced mode instead of (B)eginner, which it occurred bug in Advance mode. In Beginner mode, it does not occurred when 'no more move' made..
Update: I already test Block in (A)dvanced mode, it does not occurred the bug........ STRANGE thing, What I seeing this one he is try playing on either Atari 2600 system or Stella emulator.
it's almost 2,222 miles or less if you take I-81 S from Maine to Texas. it takes about 33 hours to drive down. Anyway, Hope you can get cart dumped if available..
