I had recently acquired a Harmony Cart and when I played my game on actual hardware it was amazing. Gameplay using an actual joystick added a whole new challenge but then something happened - the screen started rolling.
After some pointers on AtariAge I discovered my scanlines would go to 263 for a brief moment that was seemingly unnoticeable in emulation without proper viewing. After watching the scanline count it seemed random but tere was another odd situation. The top car would disappear after a bit and never return.
The only thing in common with the rain playfield and the car were they were both activated by an if/then statement tied to the score. I had deleted the whole car code and seemed to not experience a scanlines increase but my laptop battery was dying so testing will continue tomorrow.
Another thing I had an issue with was the rain. I tried using my code from before but it didn't work the same. I figured it was probably due to the fact that I am using the DPC+ kernel so the pixels are smaller and with multiple sprites and colors it was not as simple as before. The sprites appeared farther apart. To solve this I instead used a virtual sprite. It still didn't work the way I wanted but it kind of looked like lightning so I was thinking in the rain stage the lightning will come from the top of the screen and head toward the cart. You have to get the cart to the customer ASAP or risk getting fried. I may put in an option for the joy0fire button to release the cart to avoid shocking Bag Boy.
Depending on all this testing and what I want done with gameplay, I may move the difficulty back to a separate bank to provide more gameplay code in bank 2, like player 2 control.
