Re: Aladdin (Super Game) mapper 4 bug?
Is it really just about use of dark cyan ($0C) as a "midnight blue" color? If so, it has precedent. Look how cyan the background in Matthias Grünewald's The Small Crucifixion is. If you want, I could go find levels in Haunted: Halloween '85 and its sequel that also use $0C as midnight blue.

I'll check if Nestopia actually uses the MMC3A mark to modify its behavior.tepples wrote:Because no licensed games are known to rely on MMC3A behavior (as opposed to MMC3BS/MMC3C). If this game does, then a proposal for an MMC3 submapper may be in order.zeroone wrote:In my GoodNES audit, I treated mapper 1 games marked with MMC1A as mapper 155 games. Why isn't there a separate mapper for MMC3A games?
What about Star Trek - 25th Anniversary and Nintentulator?

I suppose it could just come down to the palette that's used, but here's what my emulator looks like with emphasis bits enabled:

Weird. Something's wrong here...
I already changed the way of calculating the color emphasis values. Same result. I mean... the colors are not darker like in your emu.

Re: Aladdin (Super Game) mapper 4 bug? [SOLVED]
The equations you contributed to the wiki for doing emphasis directly in RGB are wrong. You should try redoing them via YUV space to see if you even can accurately emulate them without the colorspace transform.
Re: Aladdin (Super Game) mapper 4 bug?
Unsure if there are other issues, but garbage flashes on the screen right before the dialog boxes scroll into view. But this doesn't happen in Nintendulator so... I don't know.zeroone wrote:What part of the game supposedly fails to work?thefox wrote:Yet it does.lidnariq wrote:If Nintendulator is using the old behavior, then Star Trek - 25th Anniversary is supposed to not work correctly...

I've updated the table, taken from Nintendulator.

In fact, I still don't believe that color emphasis in RGB space is... "impossible", or not interesting at all.
There's a bug in my gfx code that's NOT selecting the correct emphasis.

Interesting. How were they computed for Nintendulator?lidnariq wrote:The equations you contributed to the wiki for doing emphasis directly in RGB are wrong. You should try redoing them via YUV space to see if you even can accurately emulate them without the colorspace transform.
