Is it possible to test any homebrew app in PCSX2 emulator ?

or in another emulator ?

i don't have a ps2 but i want to begin coding for it and testing in emulators for now.

thanks for any clue.

Testing in an emulator is a VERY poor substitute for testing in the real thing. Remember that emulators generally only emulate just enough to get games to play. You could totally miss an issue that prevents it from working on a real machine, like the timing.

PCSX2 is also way too preliminary to be useful for real testing.

i would agree. its not good for development. i use it myself just to see that the elf file compile proprely, but its really slow, laggy, and has problems with 3d objects. it acts as if there was a light enable but no depth, which causes to see through an object. if your serious about dev then get a ps2(dont get the v12(psTwo slim)). but just to see if the code works, its fine for now. you will need the bios. to boot run the file tho. but your on your own on that one.

what's wrong with the v12?

If it wasn't for the v12, I'd be in some mini-itx forum right now.

I was told that the v12 doesnt work well with homebrew

There's nothing non-serious about the new playstations in terms of development. In fact, it comes with the most important thing for development: the network interface.

The only things you can't do with it is install a hard disk or boot your own code without modification. So, if you're big on an unmodified console, go dig up an old playstation 2. If you don't care about that, feel free to get the tiny, pretty new one.

i run homebrew off an 80 gig hard drive plugged into my unmodified v12
(using the sony linux disc).

and from what I read, the swap technique is easier with the v12.

I use pcsx2-0.7-dev for testing purposes and so far I'm happy with it. It saves me a lot of power-offs and power-ons and the waiting for ps2link to boot up. After all, 2D is working pretty well. Right now the speed is not an issue for me, however I found out few things that does work on the emulator, but does not on the real thing, such as unaligned numbers.

The purpose of "testing within pcsx2" is to "test the ps2 part of the software". Compiling it for pc straight and test it on pc won't help in any single bit about the ps2 part of it....

to: pixel who said anything about compiling on the pc. i compile on linux, if succesfull i compile code on the pc. but come to think about it, its not really saving much more time if your doing the direct connect to the pc. but as this guy mention he doesnt have a ps2. so the output is better my method. but still hasselsome. anyway the best suggest i guess is buy a ps2.

I just hope you mean "compiling on the ps2 linux kit"....

pixel: ps2 linux kit? no, i dont compile on the ps2 linux. i compile on the ps2sdk from my pc. isnt the ps2linux the official non commercial dev kit from sony. when i said compiling on linux i mean compling on my pc(linux), using the ps2toolchain and ps2sdk from oopo sites.

I agree on "two mains" point. I try do that most of the time, but it depends whether the project does make sense on anything but PS2. However, to have a debugger is a lifesaver :-)
