PCEP port to PS2

[ziltink]

How easy is it to port a PSP homebrew application to a PS2 application? I have recently tried the PCEP PC Engine emulator for the PSP and it seems to work great. I can't help thinking, this would be great on the PS2. I don't know how similar the hardware is, but it seems similar enough.

Any ideas? I'm just dissapointed there aren't any good TG-16/TG-CD/PC-Engine emulators for the PS2...

Hmm... I was attempting to port gpSP 0.7 to the PS2 from the PSP.... but did not go past rewriting the low level stuff (Lack of time to commit).

If you're interested:

The PS2 is similar to the PSP because both share MIPS processors (Assembly code should still work, unless it relies on certain traits in the PSP's architecture).

The PS2 has more parts, hence you need to re-write the code that interfaces with the hardware/libraries on your program. The up side of this is that you'll get better performance.

The PS2 shares almost no similar libraries with the PSP (Linked with the above point).

You should find out on how to program the PS2 first (Or how the hardware is programmed/initialized).

1 more important point: The PS2's "normal" screen ratio is 4:3, while the PSP has a 16:9 screen!
Please rewrite your program to not display anything outside the screen.

If you need more help, please feel free to ask.

Good Luck.

Where is a good place to start with PS2 coding? I am interested, but I'm unsure where to get started.

Sometimes the site is offline, but there you'll find some demos/sources.
Also, the forums here are very good.

Yea, and look for clues on Google.

Unfortunately, getting certain information on programming the Playstation 2 can indeed be quite a challenge (E.g. find out where in physical memory is KSEG0 is mapped to).

There isn't a "real" documentation for our SDK.... that's the bad part.

Of course, you can also feel free to ask the more experienced coders for advice (Me, Dlanor and some others....).

EDIT: This is an odd source for information... but look at the uLE source for anything you need to know.

Somehow a lot of stuff which I had wished to know (In the past) was found (As examples) in the uLE sources.

Cool, thanks. I will defiantly keep all of this in mind. I've tried getting on the PS2Dev site and it does appear to go up and down.

I haven't actually seen a place to get the PCEP source, I'll keep looking. The next best thing I've found is Hugo! TG/PCE emulator. It's SDL, which I assume is easier to port to PS2. I've tried it on Windows and Linux and it seems to work well enough. There is also a PSP port of Hugo! as well.

Good luck to myself!

Good luck to you! I hope you'll do something nice sooner or later.

It's SDL, which I assume is easier to port to PS2.

Sadly, the PS2 does not have a SDL library (You need to write the SDL stubs yourself!). There was one in the works, but it got stalled, and nothing was released publicly.

Incorrect. There is yes a SDL ported to PS2 available in ps2dev.org, I even use it to port my megaman-like game to PS2.
There are some problems on it, like timers and lack of sound support, but it does help for most part of code porting.
