Yeah, I have clicked it for many times. But the error keeps popping up

[stnerplc]

does anyone know how to get rid of the error that prevents you from saving?

I haven't had much time to tool with what exact version breaks the saving in this game, but I do have a work around

While I cannot create saves from a brand new game in recent versions, what I can do is take my save created in r2927 and take it over to any recent version.

When I load the save created in the older version of JPCSP in any newer version everything is fine. I can load, save, and even create new saves. Everything going good so far. No go if I start a game in newer versions with a "fresh" memory card.

Hello, Herenowit
I followed your instruction to run the game in r2927. I can save in game now, and I can select the Select Story option too! Thank you very much for your help

1. I agree, that so far the only workaround for the save issue is making the save on an older build (build 2957 works fine and is mistakenly announced as 2927 on the official website) and taking it to the newer build.
Concerning the saving issue, I have an idea on how the number of builds that needs to be tested may be reduced.
We know the followings:
a. the latest known working build is 2957 (not 2927, I tested it myself);
b. the first known bugged build is 2986;
c. Each newer build is derived from the previous build.
These 3 characteristics put us in the situation on which we are looking inside a sorted array of boolean values (true or false) which we cannot see. Because the array is sorted we can use this algorithm to find the first bugged build faster, if we are lucky, of course.

boolean workingbuild (int build){
boolean tested;
...//returns true if not bugged
return tested;
}

void findbuggedbuild (int startbuild, endbuild){
dif=endbuild-startbuild;
if((dif mod 2)==1) dif--;
neostartbuild=startbuild+(dif/2);
if(workingbuild(neostartbuild)){
findbuggedbuild (neostartbuild, endbuild);}
else{findbuggedbuild (startbuild,neostartbuild);}
}
//mod= modulo

Applying this algorithm, the first build that needs to be tested is 2971. If 2971 is bugged we need to check 2964, otherwise we need to check 2978, and so on.

2. Concerning a potential PC replacement, the new PC will definitely have Windows 8 x64. The game I am playing is this one - Final Fantasy IV Complete Collection and it is well known that its emulation makes use of a discontinued product called SonicStage CP. For things to be more concerning, this software contains a driver.
Questions:
a. Has anyone tested JPCSP with audio decoded by SonicStage CP on Windows 8 x64? Did SonicStage's installation performed normally?
I am asking these because I don't want to turn my PC into a test subject.
b.If answers are yes at both questions from 'a' which Java Runtime should I use (32 or 64-bit) and which JPCSP build (32 or 64-bit) for JPCSP to use SonicStage CP?

The save issue maybe fixed in Rev3009

The snapshot feature is very unstable when SonicStage is used. One small mistake and the emulator freezes permanently with Java error when loading from snapshot.
I suggest disabling snapshot feature when audio decoding with sonicStage is enabled until a solution is found. Sometimes, even if the emulator doesn't freeze after the snapshot load, all text is missing (from dialogues to menu options and sub menus); and if the emulator didn't freeze at first, it much probably will once the game characters leave the room / area they are in.

For final Fantasy IV Complete Collection and probably any Final Fantasy based game, these are the conditions to avoid an emulation freeze via snapshot load:
1.If you are in a battle and saved a snapshot, only load that snapshot during that battle (applies to all battles random or boss battles altogether);
2. Do not save during screen break effect before boss battles;
3.If you are in a town / village's building and saved, make sure you load the snapshot while you are in the same building;
4. If you are in a town / village outdoors and saved, make sure you load the snapshot while you are in the same town / village outdoors;
5. If you saved during a dialogue make sure you load the snapshot only when the exact same sentence spoken by the same character is shown on screen;
6. When a menu or sub menu is shown and you saved make sure you load while the same menu or sub menu is shown and the same menu item is selected. Applies to all game menus: start up menu, in game main menu and all sub menus, shopping menus and so on;
7. If you are in a dungeon and saved make sure you load snapshot while in the same room or area of the same level; be careful, complex dungeons have multiple areas / rooms located at the same level of altitude;
8. All above conditions needs to be complied simultaneously which is clearly very difficult and will definitely screw up sooner or later.

Hey all,

Does anyone experience extreme lag when battles start? The animation is similar to when glass would break. This is the only part that ever lags for me. Any help is appreciated. I am using the suggested settings from page one.

I have 6gb of DDR3 Ram , CPU: i5 3750k and an ATI Radeon HD 6850

Any help is appreciated

That glass break effect on screen occurs when a boss fight begins and is present in most newer Final Fantasy versions. Indeed, I experience that as well, I get only 1fps at those moments. My computer is much weaker than yours, it's a miracle it could run JPCSP, but there it indeed lags in a strange fashion.
