Probably a typo in the source. MAME's debugger is many times more powerful than what was available to actual developers at that time.

wow! now also the stars pattern in SNES Test Cart looks ok! great work Kale!

r5388 /src/mame/video/snes.c: [SNES]: Fixed vram size when in hires mode

Desert Fighter


r5389 /src/mame/machine/snes.c: [SNES]: hooked up interlace mode



Syvalion

(I know, sprites should be doubled in y-axis when in interlace mode...)

EDIT: and be careful about Syvalion sound, doesn't work and gives a (rather annoying) whistle...

Bug: Super Chase HQ menu. Background is all red, should be blue.

Mega Man X, with its fiendish copy protection? works! (at least the 1.0 version)

RPM Racing: Interplay logo is wrong.

Tokimeki Memorial: menus are bad screwed. (missing text)

Energy Breaker: world map is missing entirely.

Madara 2: menu is actually functional, but horribly misaligned (cursor/text it represents). Most likely a remaining hires sprite issue, because the cursor is confines to the left side of the screen.

Edit: just updated to 5390, and Madara 2 freaked out. Clean build fixes it. I suggest SVN users clean build before reporting bugs.

Another doubled y-axis issue due of interlace mode (check the system info, if it says 4** as vertical resolution then it's into that mode).

Well, you guys are kicking butt here, so I had to mention it. I don't expect it to be a valid bug for long, with the way you and etabeta78 are ripping through some of the fundamentals of rendering and register accesses.

I'm having no luck on my NES projects, so I'll see if I can't find any obvious ways to help out here

Edit 1: Probably the single biggest "quick fix" for timing being very off is that DMA takes 0 cycles. while the proper figure is (length+1) for the transfer itself, there is some overhead (I can't find byuu's *DMA data any better than I can keep up with his IRQ timing data to give exact figures)

Charles MacDonald's interlace demo from bug 786 works now too except for the (non) doubled sprites.

1843 and 1847 are likely both offset-per-tile mode even if I'm not clear wtf a "DYCP scroller" is

I thought you were the demoscene fanboy

Hey, I almost remember the purported storyline of Second Reality someone made up on USENET 15 years ago, but I've never heard that term

most regs have been added to PPU struct now. Dead Dance has lost <2% compared to rev.5355 (but I admit that I still haven't compared to 0.133)

my next task is to understand why window masking uses opposite values for color (it should not)...
