Menu cursor corruption on both Emulicious and real hardware #12

Closed haroldo-ok closed 6 years ago

haroldo-ok commented 6 years ago

As reported by Tibone:

I'm having a weird problem. the cursor is blinking all over the screen. It happens on my real SMS (model 1 60hz) and on Emulicious as well.

I uploaded the whole src folder here: (...)

I compiled it using the lastest twee2sam i downloaded from the thread.

Any idea of what might be causing this behaviour?

Thanks!

The bug has been confirmed to be happening in both recent and old versions; the cursor keeps flickering between multiple characters.

Weirdly, while the problem happens on Emulicious and, reportedly, on real hardware, it does not seem to happen on Meka 0.72. Perhaps some VDP timing issue is causing the sprites used by the cursor to become corrupted when using a more accurate emulator?
