Chrono Trigger: reoccuring gfx bug (intro)

[panzi]

When the black omen appears in the orbit of earth, there is a gfx bug which is in SOME versions ov zsnes, and in others it isn't.
In the intro you can see what I mean.
In version 5/19/05 the bug is there. In some older versions the bug is worse, in some it isn't there at all. Strange.

This is a known issue. It will get fixed eventually (or has it already been fixed in CVS?)

[snkcube]

Try using the search option next time.

(or has it already been fixed in CVS?)

Nope. Random bug occuring at compile time.
Likely never fixed unless we clean up the whole source.

I did. But there are so many entries about chrono trigger, didn't find that specific post.

I noticed this recently myself loi... while using FuSoYa's 8MB fix build...
I noticed that it is not occurring in the original v1.51 build (dated: January 24th 2007)

It's apparently an existing bug in the original code that appears
randomly at compile time:
http://board.zsnes.com/phpBB3/viewtopic.php?f=3&t=3500

Ohh if it occurs at compile time then maybe an optimization issue...
-O3 causes crash on run issues because certain functions dealing with the read and writing of the settings files were being optimized out...
but -O2 seemed to do ok .... for those issues (I may or may not have created a bug report yet I have info I have gathered at home just probably not submitted it yet.

I have been working with FoSoYa's 8MB fix src code version of ZSNES of late....

I'll try out my custom compiles (including Debugging symbols in at least one build) and see if that glitch is occurring in any of them..
and report back on it.

It seems you can get around it by disabling the "new GFX engine" option in the emulator.

ohh so a bug in the new gfx engine being randomly caused by a compiler optimization issue maybe... O_o


ps:
I would like to recommend two SVN repositories,
one if for the original v1.51/v1.52 before the GUI over hual so we can still make use of and fix it abit...

and maybe some day compile the new stuff(I haven't updated since years ago so I have broken v1.52 svn local copy...

[joe_devore]

new update.... ^_^ lol

I have discovered, when compiling zsnesw.exe from source-code ..
when I set the ASMOPT in the makefile to
-O0(which is defaulted to -O1 even for debug build....)
the reoccurring Chrono Trigger - Intro glitch ~ Black Omen scene graphical glitch does NOT =D occur O_o ^_^.

[joe_devore]

Anyway that's moot.

moot?

did you guys fix this glitch in the builds after v1.51 or v1.52? and if so do you have the code handy? ^_^
