MODE 2 not working on //e #235

Closed bobbimanners closed 1 year ago

bobbimanners commented 1 year ago

Somehow I broke it. Works on GS still.

It is crashing on 65816 code in CLREOLGS. It shouldn't be getting there. I think VDUBANK is the problem here.

Seems this got broken a while back, early in the SHR work. The last working build I could find doing a quick bisect was this one:

    Use ZP for SHR char plotting - little bit faster

This one works still:

    SHR 640 mode - support for text colours
bobbimanners commented 1 year ago

Broken in this build:

commit e2f13be9f894f42e89e5c8be79198502bc6490ec

    Scrolling works in 640 SHR mode now.
bobbimanners commented 1 year ago

Broken here too:

commit 0e746972713692adaf55b3280aac961c6b4ae266

    Fix #223. Also CLREOL (sorta) works in SHR mode.

THIS IS THE COMMIT THAT BROKE IT!

bobbimanners commented 1 year ago

OK, so managed to deduce it is SHRCLREOL that is getting invoked on the //e somehow in HGR mode and ...bang!
