No.08508 Tafoid Administrator May 6, 2012, 23:53	It's my opinion this driver should not be have been placed as "working". Some games run and look good, others have graphic issues (unknown if it's cart problem or emulation issue), others have speed problems (too fast). Rather than take multiple obvious bugs which don't seem to be regressions Testing back to mess 0.138.. the sets pictured above do the same thing - (soccer and rgmahjon from software list), even after the driver was given a working status. Has any of them ever worked correctly? I'd bet not.
No.08517 Haze Senior Tester May 8, 2012, 01:01	it does look like it might be a case of premature promotion to me, unless the majority of the sets work and these are the exceptions, although the report doesn't indicate that. I haven't looked at the driver yet, but the graphics look suspiciously like one layer should support a 'double height' tile function, which some early chips had (the majong tiles for instance. Speed sounds like it could be an irqgen issue.

No.08800 Kaylee Tester Jul 10, 2012, 18:56	Thanx for the so far. 3 errors that I found so far 1) Pole Position II Has bad graphic errors. screenshot attached 2)Super Golf gets to the select player number screen then freezes 3)Ys. The sounds seems to lock-up. producing a single note and keeping it
No.08806 Kaylee Tester Jul 16, 2012, 20:48	1) Pole Position II Has bad graphic errors. screenshot attached <--- Latest fixes fixes the graphics 2)Super Golf gets to the select player number screen then freezes <-- Latest SVN fixes the Lock-up, But get's to the select screen then ask fto press the start key, but no key assigned correspond to start. (i've tried all the keys)
No.08812 wilbert Developer Jul 17, 2012, 18:43	Yeah, I swapped the ASSERT/CLEAR signal on the line positions. I was able to actually start a game in Super Golf, let me retry that. The hanging note in Ys still seems to be there :(
No.08813 wilbert Developer Jul 17, 2012, 20:24 edited on: Jul 17, 2012, 20:25	The kungfurd set also seems to suffer from the hanging note issue, just like Ys.
