PS2 Classics : has anyone tried to reduce ISO size before conversion

[depaul]

Hi everyone.
Before converting PS2 ISOs to PS3 PKG installable format, has anyone tried to reduce ISO size with methods like : downsampling movies, removing dummy data,...etc.

Would it work in PS3?
Thanks

Should works if done properly. If PS2 don't rejecting them, emulators also shouldn't. Remember that many PS2 games using LBA tables as security level and there are also games which doesn't write to TOC all files (those games seeking data via hh:mm:ss or direct LBA access instead from TOC, i.e Final Fantasy 12), which means they will be invisible for every disc image viewers.

You underestimate sony FF12 Polish translation is game that can't even boot on PS4 if you won't fix sector count in toc, on PS3 it work by pure luck that LIMG have more rights, than real disc TOC.

But in overall many games can be shrink safely if done properly, like you already explained. PS3 care mostly to have correct data about disc sectors, everything beside that is like on PS2.

Actually... years ago was very popular some "ripkit" tools to reduce the game size from the original DVD to make them fit into a CD
I guess all that ripkits should work, i remember there was a web specialized in them that had a lot

But obviouslly that kind of huge size reductions are going to damage a bit/lot the game experience
Is not like you are removing files used "out" of the game that are not going to cause any gameplay change (videos extras, the "press start screen" intro movie, or audio for other languages you dont use)
A lot of that ripkits was removing "ingame" videos and things like that a bit destructive
Personally i like to rip the games (i even do in all my PS3 games when posible), but i never damage the "ingame" experience, thats a golden rule for me when im ripping a game

This website was probably www.alucard.cc. Dead since around 2008.

They develop two multi ripkit tools with plugin system (plugin per game/series/vfs; without them app is useless, with it is powerful).
CRC and XpertTool.

You can also find some ripkits in my PS2 AIO Project (but use virus total first for each of them, some can do more than just ripping games ;]).

Exactly that web, it was the ripkit heaven and the Xpert tool was pretty cool
Before the Xpert tool there was a lot other ripkit apps/tools designed for a specific game
All that stuff should work in the "PS2 classics" running in PS3 because well... all that ripkits was defeating all the game protections
Are the kind of tools that we are confident that are going to work fine

Btw, i dont suggest to downsample videos ever, this is the kind of thing that requires a good amount of work and time, specially because every game could use his own formats, or it could have his specific restrictions (maybe there is a game function that have hardcoded the original video file sizes and when you replace them you break the game)
Also, is the kind of thing that when you are doing it for first time in a specific game you dont know if is going to work. Is needed to do it by the test-and-error method

All and all... it requires lot of time, and is not worthy because you are lowering the video quality, so i consider is butchering, reducing video quality damages the game experience
