but in fact there are mostly talking about assembly code...so I wont translate it except if someone ask me for...

see you :lol:

Please do

so here you are :
thunderZ : only ARM is better and to be honest I never used THUMB with GP32

I agree but with GBA the THUMB instructions are more used than with GP32 because the cartridges are read in 16bits so it needs 2 read to make 1 instructions in ARM.
The Pb is : if I replace SWI by BL then I need to be carful because SWI is switching by itself the CPU mode to ARM but BL doesnt and it could call a fonction written in ARM using THUMB.
This is the reason why I said I should write everything in both ARM & THUMB.
Now I must admit nothing forbid me to write in the THUMB fonction core a BX to an equivalent ARM function.

Actually with the BIOS mod I can bypass that and I will work on that later.

Another question : about timers
I need to cause a timer at each lines from the LCD in order to refresh all the video registers...unfortunaly GpTimerOptSet doesnt seem to enjoy a lot of ticks / second so Im refreshing VSYNC after 32lines and sometimes that causes Pb.
Can we bypass this limit?
Did someone already make a function to configure timers?

In the worst case I got sources to conf timers without the SDK
(http://www.deadcoderssociety.tk/ a prog emulating VSYNC)
By reading the Samsung doc maybe I can find a way to conf timers using a BRUTE FORCE method ( a barbarian one )

see you :lol:


EDIT : I dont know a lot about ARM and THUMB so maybe I made some mistakes while translating....I hope this wont interfere with a global comprehension
When news will be talking about the emu itself then I will take more time (and I hope there will be less mistakes )

THANKS Washo!
hope more usable news soon or a first screenshots.

 

[pip]

Thank thee

 

[Squidge]

Sounds like he needs to use Mr Spiv's VBL code ! Or access ARM timers directly to get more resolution.

 

[Wolfsclaw]

gba and psx emus in developement now everyone should know that the gp32 is faaaar away from death

 

[Sonic-NKT]

yes the scene is pretty active again in the last time...
also many things from new devvers...
gba emu, Racing game etc..
but also the "old" devvers are still working on it...
Cant wait to see where we are in 1 Year.. perhaps first xbox emus?
*only joking*

Pour vous donner un tout petit avant goût, j'ai fait une toute première pre-pre-pre-alpha-release : vous la trouverez sur www.chez.com/shubaca
Notez bien le pre-pre-pre !

N'espérez pas trop faire marcher des autres demos que celles qui sont dans le zip

to give you a quick pre - taste here is the very 1st pre pre alpha release
dont hope to run anything not in the zip...


FIRST ALPHA OUT : http://www.chez.com/shubaca/

note this is a PRE PRE PRE alpha release

see you :lol:

 

[CU_AMiGA]

That's great. I didn't think it could be done! How well does it run the demos?

 

[jegHegy]

i'm browsing through old demos. i find running this: http://www.gbadev.org/download.php?section...=LeonardGBA.zip at twice the original speed is quite impressive.

 

[washo]

arf : link failure

btw : http://gbadev.org/demos.php?year=01&month=08
glass.zip works

ok, i havent been following this thread too closely... but is it safe to run this on a real gp32? or does it modify the bios?

 

[Mark]

I'll be testing this shortly, then smiling when I think of future versions

 

[declaration]

Does anybody know how to get the provided ROM converter working. Mine doesnt ( I don't think ).

 

[washo]

of course : just DL the one available at the same page than the emu
if your gp32 reboot then you will have to wait till the next version
(run a DOS box then type : ROM_... gba.gba gp32.gpa)

you wont have to mod anything....you can go...

see you :lol:

 

[Vimacs]

one more working demo http://www.gbadev.org/demos.php Mode5 Rotoxxxx

ah thankyou. I was just typing the wrong thing. Stupid me.

Thanks for the demo btw. Its very very promising and exciting so far.

 

[washo]

one plasma demo worlks sooo fast (maybe 4-5x than the original....'using virtualboyADV'
the zip name is : armplasm.zip
also 3dplotb.zip and z.zip everything from http://www.gbadev.org/

see you :lol:

 

[Tobriand]

Both 3DPlot mode 4 and mode 5 work very nice. And there's a mode 4 magnify demo that looks great. This emu, despite being in its early stages, rocks. It rocks a LOT. This is further than I ever thought the GP32 could manage. Well, not EVER thought the GP32 could manage, but for quite a long time at least.

Thank you ENF65 (I hope I got your name right lol).


Unfortunately, MetalSlug Advance (a PD one) crashes. But to be honest, I expected that. Had to give it a go though. Just to try.

Anyone know any games that use only the supported modes, as opposed to demos? I doubt it, but hey, someone might!

EDIT: Just tried Leonard 3D - and been absolutely astounded! How on earth can it be that FAST?
