Transparency Bug with Super Punch Out

Schnuffelduffel · Post by **Schnuffelduffel** » Fri Oct 01, 2004 2:06 pm

Hello

I've found a transparency bug
zsnes has this bug since the early dos versions

in super punch out, when u knock down an opponent
and the referee starts to count
1-2-3-4....
the numbers are not transparent !

with the orginal snes and with snes9x the numbers are transparent

i tested this with the us rom :crc e2f92f84
and the european rom : crc c6906f5f

i use latest wip version
and play with 1280x1024 ds full
triple buffering and interpolation

i testet all other video options but the numbers are still not transperent

Probably won't do a thing, but try using the old gfx engine (press "8").

Advice: the PNG format is much more appropriate for screenshots than the BMP one... Much smaller files, same quality.
The BMP format shouldn't even be used on the net... This forum system won't even display them anyway, as you can see.

I believe TRAC has the exact same problem in SNEeSe, he was asking me about it one night.
Can a note be made in a bugreport to send the fix to TRAC when it is found?

Fixed, found a very stupid mistake in the code. But the numbers do not have the italic effect like they should, not really how they are getting like that.

good news that its fixed

i hope the fix is included in the next wip version

It's not 100% fixed yet. I am still looking into why the numbers are not italic.

zsnes has this bug since the old dos versions
but i am confident that u'll find the bug soon

snes9x and snesgt don't have this bug
may be it helps to look at there source codes
even if they are different to zsnes

(may be this bug with the transparency has an effect on other games too)

Looking at other emulator source code is useless until you actually KNOW what causes the problem and what you're trying to fix.

Pagefault doesn't know what the problem is yet, so looking at other source code is useless since you don't know what area you need to look at.

He'll need to figure out WHY the numbers don't come out correct first. Is it HDMA, is it timing, is it a register? Once he figures that out, he can look at other source code for how it's emulated IF necessary.

It's just not as simple as SNES9x has it right, so just look at that. That alone doesn't help much at all.

It also doesn't help if the other emulator lacks source or that particular emulator has a hack to get it to display properly for that game.

There hasn't been a mention that Super Punch Out was fixed.. only that the hack used for it is removed.

I'm not surprised. I will move this thread so people are aware of this.
