DEED Posted March 3, 2006 Share Posted March 3, 2006 Now I'm no programer but I've been thinking, would it be posible to create some sort of program for psp that will read .gta extension files and play them, then users wouldn't have to load gta to listen to music or have two music files on there psp. Though it may not be able because they've got some sort of encyption. DEED Link to comment Share on other sites More sharing options...
GW2 Posted March 3, 2006 Share Posted March 3, 2006 i think it would be better if edison carter added mp3 playing function to the cheat device so you could listen to your music while in gta without the stupid conversion. Link to comment Share on other sites More sharing options...
K^2 Posted March 3, 2006 Share Posted March 3, 2006 (edited) i think it would be better if edison carter added mp3 playing function to the cheat device so you could listen to your music while in gta without the stupid conversion. That would most likely be very time consuming. Unless PSP's OS allows for some shortcut, he would have to open the file, read the header, grab the MP3 stream, send it to a decoder, get the PCM stream from the decoder, and then add the PCM stream to the sound output buffer. I would imagine that people who work with PSP code would know how to access the PSP's MP3 decoder, so that shouldn't be too much of a problem, but working with sound output buffer might be a lot more complicated. Most likely, it would be possible to get the pointer to the currently played buffer from the OS, but there can still be problems when the buffers are swaped, and it might be tricky to tell which part of the current buffer to write to. Most of my experience with sound playback comes from Windows programming, though, so I might be missing something that could make this a lot simplier or a lot more complex. Edit: The problem with output can be simplified greatly if PSP's OS allows for multiple virtual sound output devices each of which would work with its own buffer and the mixed sound from all such virtual devices would be sent to the speakers. If it would then be possible to add another such virtual device on the fly specifically for MP3 playback, then, provided that the MP3 decoder is easy enough to work with, it might drive the development time down to a couple of days.

Yer I thought that too but like K^2 I think it'd be alot harder, though I think it is a better idea. The reason I really want this is if i'm listening to music: 1. I have to have the game on me. 2. I have to wait for the game to load. 3. I can't skip tracks unless it's in play. 4. There is no seek etc. 5. Many, many other problems. Mabie someone could make one using the offline browser? Damn this Topic pobally should of been posted in "General Discussion" oh well... Link to comment Share on other sites More sharing options...
etnies419 Posted March 3, 2006 Share Posted March 3, 2006 I know the answer is probably no, but if you could chnge the file extension of something other than music to .gta, would it load. If so, that could lead to an even better cheat device. Link to comment Share on other sites More sharing options...
Sektor Posted March 3, 2006 Share Posted March 3, 2006 If it's not in AT3 format (.GTA), it will just look like corrupt data to the game and LCS will ignore it. Link to comment Share on other sites More sharing options...

No, what I mean is, say you take a text document. Now when you save it, change the extension to .gta. Then put it in hte custom tracks folder. Would it be possible to run something using that method?

Impz2002 Posted March 3, 2006 Share Posted March 3, 2006 No, Its just an audio stream and it doesnt execute any commands. impz Link to comment Share on other sites More sharing options...
Sektor Posted March 4, 2006 Share Posted March 4, 2006 (edited) Firmware 1.5 users can now play MP3s during any game using iR Shell. It won't work for 2.0+ users. edit: if official iR shell site is down, you can download it here. Edited March 6, 2006 by Sektor Link to comment Share on other sites More sharing options...

DEED Posted March 4, 2006 Author Share Posted March 4, 2006 Too bad GTA LCS requires 2.00 . DEED Link to comment Share on other sites More sharing options...
Sektor Posted March 6, 2006 Share Posted March 6, 2006 LCS can work on 1.5. There was a method for playing the ISO on a 1.5 before your post and now there is a method for playing from the UMD. Multiplayer and Cheatdevice don't currently work on 1.5 though. Link to comment Share on other sites More sharing options...
K^2 Posted March 6, 2006 Share Posted March 6, 2006 Could you launch IR Shell using the exploit in GTA save games? Or does it actually require 1.5 firmware?

Multiplayer and Cheatdevice don't currently work on 1.5 though. Actually I heard about this, I should of mentioned that. But now that there is a way for 1.5 to play UMD version of GTA thats pretty cool. I've got v2.00 and I'm thinking of downgrading. Only thing is I think I need a bigger mem stick first (still got the 32mb stick), the reason? because i only got GTA & Fired Up and when i downgrade to get hombrew ill need a game to keep my psp interesting(Fired Up doesn't count coz its REALLY BAD - at least it had a browser so if i am on v1.5) (on that thought I'm thinking about getting SOCOM). I've had a look at iR Shell and it looks great! I'd just like to know how much room it takes on the mem stick? EDIT: Glad to see this topic's not disapered yet, almost got lost down the second page.

I don't think user mode allows low enough access but I could be wrong. Part of eloader v0.9 is able to stay in memory on 2.0 when launching homebrew (the quit hotkey) but i'm not sure if such hooks can work with UMDs. I haven't actually used iR Shell, it will probably slow GTA down a bit but hopefully it's fine at 333mhz. Edited March 9, 2006 by Sektor Link to comment Share on other sites More sharing options...
Faye Posted March 6, 2006 Share Posted March 6, 2006 There is a homebrew app that can convert and play most types of music. http://pspupdates.qj.net Look there before making topics. ~Fenn Link to comment Share on other sites More sharing options...

Anyway I downgraded my PSP to 1.50 got iR Shell, but when you play mp3 and play your game at the same time the game music gets all lagged and it sound really bad. Also wilst playing GTA on 1.50 is possible, it quite frankly just sucks. It compromises with some of the great elements of GTA: LCS, there is no Multiplayer, Cheatdevice, etc. Is it just not possible to create a program that will work on 2.00 that will read .gta files??? .

xxadrenaline Posted March 27, 2006 Share Posted March 27, 2006 You can put your CD tracks on your Liberty City Stories game with the Rockstar Games Converter. It does take up a lot of memory though, so don't put too many songs on. http://www.rockstargames.com/libertycityst...RCT_Install.zip Link to comment Share on other sites More sharing options...
The-end Posted March 27, 2006 Share Posted March 27, 2006 That isn't what he ius looking for, he's is looking for say an exploit in the web browser to load his .gta files..... - The-end Link to comment Share on other sites More sharing options...
