Has anyone tried to run this demo on a real V9990 hardware?

Oh, that's not good...

Any idea whats the issue here? On openMSX with gfx9000 extension it works perfectly.

@erpirao Can you please try this ROM (https://webmsx.org/?PRESETS=V9990&ROM=https://github.com/aoi...) ? It was tested working on a Powergraph Light.

@albs_br So far, I've never come across anything that works on OpenMSX/WebMSX but not on a real V9990 cartridge.
From the video, the program seems to crash (not just a graphics corruption) so if I were to look for a lead, I would look at the status or interrupt register handling.

hello, for a while I will not be able to do tests with the powergraph v9990, it seems that there is a damaged Vram module.
Sorry I can't help during this time.

So the bug on the video don't come from the albs_br's tech demo code?

Another user who has the same problem, when I have a video, I will upload it.
. I mean that the rom fails like me, not that the v9990 is damaged.
