Making a 3 wheeler is possible, i've made a peel p50 before and it works just fine, though i have never tried a central front wheel before

Excellent news. I'll give it a try for science. I've been messing around with body roll and handling params on base game cars to see if I can achieve that 3-wheeler "tippy" handling but so far I've only managed unrealistic - albeit interesting - results. Not sure if its possible or if you have any advice, but I'll keep messing around with it to see what I can discover
 
Hey, did you or anyone else manage to fix this? I’ve also been trying to decompile and mod A-Spec. I decompile GT2.VOL using GTVolTool, then GT2DataSplitter, but when I recompile the files back, some of the engine sounds break (they make a high-pitched “wooo” noise).

The best example is on the demo replay 2, the Datsun Cherry's engine noise is messed up and the car in 5th goes flying away as soon as the race starts.

It's an issue with GT2DataSplitter because if I recompile the GTVolTool files straight away it works fine. It even happens if I don't modify any of the csv files at all, I just decompile and recompile them and it still happens.

Please help.

I been experimenting with modding on top of a-spec on the last couple of days and I hit a roadblock where after I recompile my changes the game starts acting weird, the demo replays have cars not moving or fully acting erratic, some rally ghosts are broken and the most notable issue is with tire upgrades on many cars, for example if I get super softs on the F50, they get installed on the front but the rear ends up with random tires that were never purchased, even changing to the super softs don't work at all, it reverts back after the race. (pictured in the spoiler below)

All the changes I've done were to the event prize cars. Extracted the a-spec GT2.VOL with GTVolToolGui, used GT2DataSplitter to decompile the files I wanted to change, recompiled it back with the same tools, and used IsoFileReplace to put the GT2.VOL back in the game image.
Am I doing this wrong?

The woo noise is the default noise when it can't find a sound file, if you change anything in DataSplitter it breaks the existing pre-recorded demo replays.

As an FYI A-Spec is a bit unstable so personally I wouldn't recommend using it as a base because it will be harder to tell what you've broken and what's already broken in the A-Spec release.

The tool makes a best effort to preserve the order of the parts when creating the CSV files, but if particularly odd changes were made in the edited file like forcing an invalid order of parts by putting parts for one car in the folder for a different car it won't be able to reproduce that. I would expect bad edits like that to cause bugs in the game though.
 
I figure that if I replace the default noise with something less UFO-like, it will at least mask the problem.

Do you have any idea which engine noise file is the default one? I tried replacing 00000.es and 00000_n0.es, etc., with another engine file, but no luck. I’ll keep trying with the other files.

I can live with the broken demos but the sound I really want to fix.

I'm not sure, just another thing. Are you editing the CSV in NotePad? If you are editing it in Excel it breaks

It's the absence of a sound file rather than a specific file. Each sound has NA and turbo versions, and the default sound happens where the appropriate file is missing. It may be that the car has gained or lost a turbo and its selected sound only has a NA or turbo version, whichever one doesn't match.

I'm curious now as to how the carparam files can be so broken that the tool can't convert them to CSV properly, it's not a hugely complicated file format. Are you sure you're not genuinely missing some sound files? I don't know if A-Spec adds any new car sounds but is it possible that the sound used by that car is not in your new VOL?
 
So 00000.es/00001.es etc is the default?

I'm certain all the files are there because I started again with a working base A-Spec GT2.VOL, decompiled it with GTVolTool and then GT2DataSplitter, then recompiled the files without making any changes whatsoever and still have the same issue. It's the same cars that don't work each time (Datsun Cherry and Xsara Rally car + probably others I haven't found yet)

Both of those cars sound fine before being decompiled.

I think I might copy a working car's files and change the ID reference to whatever the Datsun/Xsara is and see if that works but it will be a hassle.

No. If the car uses, for example, sound ID 21108, it uses 21108_n0.es through n3 if it's NA, t0 through t3 if turbo, depending on the exhaust upgrade level. In the case of 21108, all of the turbo sounds are missing / 4kb placeholders, so if a car with that sound ID has a turbo equipped, it'll play that placeholder sound.

Presumably the Cherry and Xsara in your modified files are using sound IDs which don't have appropriate sounds for whatever aspiration type they're ending up with.
