Summary 08617: All games in sega/chihiro.cpp, possibly all sets in microsoft/xbox.cpp: Graphics goes blank
Description Starting any game in Chihiro won't draw anything (either blank or garbage data)
Steps To Reproduce - mamefoo outr2
- Wait until 2 seconds of effective time, should already draw the Chihiro logo.
To mass test, use mamefoo outr2 -bench 2
Additional Information Suspected breakage between 0.250 and 0.251
microsoft/xbox.cpp looks similar (when you have an HDD dashboard), the only GFX it manages to draw is the spinning Xbox Live disc loader (which doesn't make sense since unattended it should draw the dashboard itself with the language selector).

Not sure what 'mamefoo' is, assumed to be mame.

Could confirm the outr2 problem. Firstly random coloured areas and dots, followed by blackness.

>mame outr2 -str 5

I don't have whatever xbox software you're referring to, so I got the usual message about the Xbox requiring service.

>mame xbox -str 5

The item (null) is a square box, assumed to be a null character.

I'll confirm it on the basis of what outr2 is doing.

Just the white disk thing slowly turning.
