Hacking [RELEASE] ScummVM

[cpasjuste]

Hi,

Here is a port of the excellent scummvm engine to the ps vita. The port is now in an usable state, and is working very fine on the vita. There's still a few things to improve (add touch support, flac support ?). For a list of compatible games see : http://scummvm.org/compatibility/

I really want to thanks Xavier from consoleX for sending me a free ps vita for development !

See you soon,
Cpasjuste.

OH GOD YES!
Please give me a beta build of it.

 

[VitaType]

Fantastic news, will it support touchscreen or touchpad for mouse movement and clicking in the future?
Don't forget to enjoy your new Vita over all the development, there are some nice native games for it too (including a good port of the Day of the Tentacle remake), you really earned it

 

[Joe007]

Wow this is awesome the thought of playing broken sword games on vita woot .

 

[Deleted User]

Great, can't wait to test it.
Thank you.

 

[cpasjuste]

Thanks for all your positive feedback ! You can now test the engine yourself !

By the way, i don't know how to change the title of the thread

 

[DinohScene]

Report the thread and ask for a title change

 

[Onepunchbruh]

what emulator is this?

[Dinoster]

Been waiting for this since the release of the Vita!
You guys are awesome. Can't wait for the next builds.

Cheers!!

Nice to see psp devs here great work @cpasjuste

 

[Ikilledzeus]

This is amazing, does that mean I can play the neverhood on my vita? =D

 

[cpasjuste]

Well, there's a lot of games not working, but a lot are working too. I guess i should try to make a list but i have to get those games... I think we should have better compatibilty with retail/untouched games (files). At least i tried the broken sword demo and it worked ! Indiana jones, days of the tentacles and monkey island 1 demos are not working, didn't test the full games (monkey island amiga should work i guess).

Tested:
Monkey Island 1 (talkie version) - not working yet
Monkey Island 2 (talkie version) - not working yet
Monkey Island 3 - not working yet
Beneath a Steel Sky - works!

@cpasjuste, just out of curiosity - what makes one game to work (specially those freebies on the official ScummVM website) and the others to fail?

I still don't know, but i'm sure i'll find this soon. Else note that broken swords games works, which are good games !

the trick is disabling the arm assembly

if you use the scummvm configure script: around line 2140 at
echo_n "Checking host CPU architecture... "
add a case for the vita:
# psvita does not like the asm code...
arm-vita-eabi)
;;

then scumm games also work (MI3 works at full speed @333MHz). Took a bit of searching.

I already did a bit of research into modules and cursor transparency for 16-bit modes but no success yet.

Woot, this make much sense, i'm almost sure you're right ! Many thanks for the tips, let's try

I already pushed some changes (https://github.com/Cpasjuste/scummvm/commits/master) including 444mhz bus, broken swords runs much better for example. Else help will be more than welcome, feel free to push some pull requests

Damn, the MI trilogy is my go-to for testing ScummVM. Steel Sky is always a good one though, I'm gonna get on it :-)

Thanks @cpasjuste I look forward to seeing how this turns out.

Amazing, just out and already improving! When SCUMM games work will you recompile? Thanks

 

[cpasjuste]

Updated first post with new version which fix all games, thanks Lousyphreak !

 

[Sega dude]

Does this port support Humongous Entertainment games?
