FreeBSD 5.3, Athlon XP 2400+, 512 MB RAM, X.org 6.8.1, KDE 3.3.2

ZSNES crashes before it can even load. I installed ZSNES via the FreeBSD ports system. Here's what it says when I try to load it:

Happens at the beginning of the game, after the Nintendo logo disappears,at the very beginning of the short "movie". Can be bypassed if you press either Start or A (forget which one, the button you press to go to the File Select screen). Also happens VERY shortly after starting a new game. Bug not present in 1.42 official.

I already reported this bug, and it has since been fixed. It was caused by a problem with 'SRAM Check+Save'. See pagefault's new build in the WIP thread here.

OK, thanks. I'll try out that build, then.

I have an Append to make to that "SRAM Check+Save" Bug.
This might not be the same Bug bug??
I just download the Special PageFault Build.
Big File?? haha.
oh well, on to the problem.

This seems to happen on and off, confusing??????
I Disable "SRAM CHECK+SAVE," then reset it works.
I reenable it it still works, Dosen't make any sense.
The "SRAM CHECK+SAVE," might not completely the bug.
Maybe there is maybe there isn't, ????

Well keep this in mind any way.
--------------------------------------------------------------------------

Oh yeah btw,
You all remember that Sound Interpolation Bug I report in great detail
awhile back, its still there...

I used the Above game to test it this time,
No problem before any sound starts as before, After sound starts
Try to enable or disable, results in FULL CRASH as before.

Occurs in 1.42 and post-WIPs (including 2/07 WIP)

Savestate not able to load properly under SRM Check+Save in DOS/Windows port.

To reproduce:
1) Load ZSNES
2) Make sure SRM Check+Save is not enabled, the Snapshots directory can be undefined or defined to any other valid directory other than the ZSNES directory, and that there are no savestates in the ZSNES directory
3) Load a game (best to use a game that does use SRM aka "battery backup" like FF2)
4) Save a state (via F2)
5) Quit ZSNES
6) Load ZSNES
7) Enable SRM Check+Save

Load same game used in Step 3
9) Load save state immediately (via F4)
10) Wait approximately 10 secs
11) Attempt to load save state

You will get an error message at this point. Seems to only occur in the Windows+DOS port.

If you attempt to save a savestate at this point, you will find a savestate in the ZSNES directory.

This does NOT occur when using the save/load state features in the GUI. (If you substitude the load savestate via the GUI, there is no problem.) This is probably a directory problem. (ZSNES tries to find the savestate in the ZSNES directory instead of the snapshots/savedir.. which is the actual bug)

Another bug occuring in the Windows/DOS port (1.42 through 2/07 WIP):
When you start ZSNES for the first time (meaning there are no ZSNES generated files in the directory ZSNES is run, and you just load the GUI), and then you define the savedir path (with a valid directory of course)... if you select a ROM via Load (in the GUI)... the current savedir is redefined as the directory where you have selected your ROM from..

To reproduce:
1) Start ZSNES to the GUI like if it were your first time (remove all zsnes .cfg and .dat files)
2) Define Savedir via the Paths menu to a valid directory
3) Select your ROM via the Load menu, the ROM must NOT be in the same directory ZSNES is in
4) Pause the game by visiting the GUI (via ESC key)
5) Look at the Savedir directory via the Paths menu

Obviously the Savedir path should not change when you select a ROM and change directories AND on the first time ZSNES initializes.

BUG: F3 menu reacts strangely to the cursor keys (DOS)

Example: I'm at slot 0 and select slot 1, then press Enter. The F3 menu disappears. Now when I press F2, ZSNES saves to slot 2.

Deathlike2 · Post by **Deathlike2** » Fri Feb 11, 2005 1:35 am

This first bug in my original post hasn't been fixed in the new 2/10 WIP version.

Savestate not able to load properly under SRM Check+Save in Windows+DOS port.

To reproduce:
1) Load ZSNES
2) Make sure SRM Check+Save is not enabled, the Snapshots directory can be undefined or defined to any other valid directory other than the ZSNES directory, and that there are no savestates in the ZSNES directory
3) Load a game (best to use a game that does use SRM aka "battery backup" like FF2)
4) Save a state (via F2)
5) Quit ZSNES
6) Load ZSNES
7) Enable SRM Check+Save
Load same game used in Step 3
9) Load save state immediately (via F4)
10) Wait approximately 10 secs
11) Attempt to load save state

You will get an error message at this point. Seems to only occur in the Windows+DOS port.

If you attempt to save a savestate at this point, you will find a savestate in the ZSNES directory.

This does NOT occur when using the save/load state features in the GUI. (If you substitute the load savestate via the GUI, there is no problem.) This is probably a directory problem. (ZSNES tries to find the savestate in the ZSNES directory instead of the snapshots/savedir.. which is the actual bug)

I've found some interesting details though..

Also, if you hit F3 (after step 10), then it works normally.

If you goto the GUI after the bug occurs (after step 10), it works normally as well.

The part of the bug that is obvious.. ZSNES somehow changes the Savestate dir in memory after 10 secs occur (under the steps I have laid out). Perhaps, it is forgetting to change certain variables when SRM Check+Save is enabled when no ROM is loaded. It works fine when you change the option when the ROM is loaded.

A different bug though (occurs in Windows+DOS port and in 1.42 through 2/10 WIPs):

It is impossible to directly change to Interpolation when you have already selected another filter. However, you can change to any filter from Interpolation. Eg.

Interpolation -> HQ mode = OK
Interpolation -> Super2xsai = OK
But
HQ mode -> Interpolation = NOT OK
Super2xsai -> Interpolation = NOT OK

I'm going to hold off on mentioning any news bugs since it just seems transprancy addition and subtraction (am I right?) isn't fully implemented..

However, I fear that the Chrono Trigger bug I mentioned earlier will be on the backburner. It's the bug where you run away.. and when you succeed, the menu "loses" its transparancy during the mosaic effect.

This ONLY occurs on the new graphics engine (since it debut, the old graphics engine has no problems).

Do you still have the FF3 one like this. Apparently all the windowing fixes I am doing are related to all of this.

FitzRoy · Post by **FitzRoy** » Tue Apr 05, 2005 9:01 pm

Couple of wierd bugs to report in Final Fight (J). Capcom intro has a bunch of garbage in it when the rom loads. Only happens to Final Fight (J), but not the (U) or (E) versions.

Also, on the title screen, you'll see that the copyright text at the bottom gets cut off by 1 or 2 lines. Note that in the screenshot, the garbled stuff at the top isn't seen in actual play, but when the f1 menu is activated, you can see it (and thus it appears on the screenshot). So it apparently has something to do with the text cutoff... especially since it is the same two colors as the bottom text.

Neither occurs in Super Sleuth.

FF3 seems to be fine since the original fix (all WIPs 2/24 - 4/04). Of course not of those fixes have affected (or changed) this Chrono Trigger bug.

What ZSNES version are you using FitzRoy?

FitzRoy · Post by **FitzRoy** » Wed Apr 06, 2005 4:02 am

The apr 04 wip, but it happens in older versions, too. I don't know if it's always been around, but I suspect they're pretty old bugs.

EDIT: Ok, I just spent the last 20 minutes tracking down where the first bug first shows up. It appears in the 11/01/2003 Pre 1.40 WIP, after 10/28/03.

Secret of Evermore (U)
ROM Crash
ZSNESW post 1.42 04/11 WIP
Windows XP SP2

When loading SoE from a specific room right before the Mystic Woods under the Chessboard Maze, it will lose sound after you enter the Mystic Woods. If you try to go back to the save room, the screen goes blank. If you enter the Chessboard Interior and go back, things are fine. It also works fine if you load from the SRM.

This bug does not occur under ZSNESW 1.42 official, even when loading the savestate created by the 04/11 WIP.

To see the bug, just load the save state, go south one room, then go back north. You will lose sound when you go south, and crash when you go back north.

Volume Control Issues
ZSNESW 04/11 WIP

The volume control does not seem to affect all the sound channels. I posted before, but the problem wasn't as clear as it is in the savestate I have now. I thought volume level 0 should be mute. It was never decreasing the volume by very much.

If you load the savestate and turn the volumne down slowly to 0, you can see that some of the music disappears, but some of it doesn't seem to be affected at all.

I'm not sure if this is already in Bugzilla, since it seems to be down right now. It's complaining it can't connect to the database.

It is however in sourceforge for zsnes 1.337. It's still present in the 1.42 04/11 WIP for Windows.

http://sourceforge.net/tracker/?group_i ... aid=487184

I have a savestate demonstrating it, too.

Just load the state, talk to the guy standing there, and let the fight begin. The cursor will be half-missing in the middle, completely gone at the top of the menu, and present towards the bottom.
