Playstation Emulation

[Vollgasasi]

well i didn't mean that these previews should be on the top of the to-do list. of course emulating the games well comes first. i only wanted to know if its even possible to do it or if this is some kind of sony-psp only stuff.

I guess it could be useful for quickly identifying a game, rather than reading the name. It's not that complicated, so I'd expect it to be added at some point.

I like preview screenshot images of games before play, but it's not important and should not be focused on atm. Compatibility first people then the fansy stuff

I also like the idea of CSO compression format, I have a lot of games that I played on my psp that are in this format still.

I'm looking forward to seeing how sharp the games look on the Pandora. Tinnus will have some neat filters happening that will put the PSP POPS to shame.

 

[Tinnus]

Why would you folks want CSO? There's no other PS1 emulator that supports this format, and we'd already have the eboot and Z formats for zipped images.

Just curious. If it makes any sense, we'll look forward to supporting it

You have PSP ISO's in that format.

You don't have a single PSX game in CSO though.

Tinnus - you are correct, CSO support makes no sense - people get confused I guess.

I'd rather have official covers for each rom than a preview movie. Nothing can beat cover browsing with the touchscreen!

I believe that the same compression code used on EBOOTed ISOs is what is used to compress ISO/CSO so it shouldn't be a lot more work. Tools for converting ISO to CSO are available with source.

Correct me if I'm wrong, but as far as I was aware PocketISO is what is used to create .Z/.ZNX files - and that's a closed source Windows only tool.

I'll always favour the open solution. Just a thought, we've got a USB port on the Pandora - wouldn't it be nice to plug in a USB CD drive, grab an original PSX CD and be able to rip it directly as a compressed image from within the emulator?

 

[Tinnus]

What I'm saying is that the eboot format has compression, bells and whistles, and there are open (as in GPL) apps to do the conversion. AND we'll release a version of a converter that only does what we need for psx4all (ie: no base.pbp needed). You could also rename your final file as mygame.pbp instead of eboot.pbp to lessen possible confusion or if there's any reason to avoid PSP references because (unlike the PSP which has reasons for it) we don't care about the exact file name, except for filtering the file list by extension.

Sounds like the perfect solution. Since you're supporting both uncompressed ISOs and (what appears to be the best format of) compressed ISOs, I don't see how anybody could ask for more. Great work as always

I own a PSP, there's no reason other than a desire to see things done cleaner. Eboot simply isn't elegant - it grates with me (Although I've spent many hours making "perfect" eboots with title icons, cover art backgrounds, title music, video and loading screen rips) Raw ISO is inefficient on space. I'd love to see the Pandora PSX emulator support a nice clean compressed ISO format.

PicoDrive has CSO support...

What is it about Eboot that you dislike? What about the format do you find inelegant? If your only quibble is with all the metadata that is frequently not included in downloaded images, remember that PSX4Pandora is not likely to support most of it anyway. You won't even know that all the extra media isn't there because it won't show up in the loader either way.

 

[cools]

As an executable/data wrapper for the PSP there's nothing wrong with it.

On a system where the executable part is simply unusable it feels wrong - it's like creating a self-extracting slideshow out of a load of JPEG images, and writing a viewer on a different architecture that is only capable of viewing the images when packaged - not unpacked.

In no way am I trying to discourage eboot support - I dislike it but I know that's my opinion. I'd just like a bare, compressed ISO format available to use too.

 

[TyBO!]

Great to hear you're supporting the Eboot compression format!

I know beggars can't be choosers, but it would also be nice to see support for ECM compression format. It might be difficult to do, since it's designed to aid the compression of an ISO when using a more general compression format like WinRAR or 7zip. The good news however, is that the format is free and open-source.

That seems to only make sense for BIN images, that have extra space etc. I think you could just use ISO or something instead...

About those complaining about eboot not "feeling right", just forget what it is. Just think it would be a 600Mb CD image with a 50KB useless header (which means, it doesn't make any freaking difference)

Maybe you could think of it as "the PBP PS1 image storing and compression format", does that sound better?

Some people are really amazing. It's as if you spent all day baking a delicious pie with hand picked fruit and fresh ingredients, and hand delivered it to their house. When you showed up at their door with the free, tasty pie and said "Here, this is for you", all they could think to say is "What, no whipped cream?"

It is more like they did not like the fact that you brought a fork and spoon, when all they want is a spoon. Which seems worse to me.

The simplest way to support compressed filesystems is to support filesystems in general. CramFS and SquashFS can be mounted somewhere and used like plain iso or the real cd's. Both support compression, the latter supports lzma (7zip).

How will the two other shoulder buttons on the PSX controller be handled? IIRC, the Pandora only has one set of shoulder buttons...

 

[xinfernoofdantex]

yay for eboots =]

Whatever you map them to There's PLENTY of other buttons. Moreover, you could map the shoulder to L2/R2 if they fit better and put L1 and R1 somewhere else, and so on.
