Uae4All2-SDL Amiga Emulator for Android

[Higgy]

28 MHz it fly's! Maybe too quick.
What a frustrating little game that Jumping Jack
I think you need perfect timing for the jumps. Maybe it was a bit slow on Spectrum?

I have a weird problem with Hacker's Keyboard.

My tablet has a AllWinner 4 cores CPU, a 8 cores GPU, and a Retina screen.
The two times i tried the hacker's keyboard, i found it very slow in landscape mode (in portrait mode seems to run well).

See ya!


P.D: I think it would be awesome to have a real Amiga's virtual keyboard, just as the Android one, but with all the Amiga keys .

P.D 2: Yesterday i tested Deluxe Galaga, both ECS and AGA versions.
With the A500 preset, the ECS version doesn't load.
With the A1200 preset, the AGA version works but the graphics are weird.

@lubomyr: I try later assign some custom controls. And like I remember from early version setting buttons position was not too good because buttons can be places in strange position by hand, so I prefer to use default one.

Sorry stupid tablet mucked up my last post.
56 and 112 MHz is slower than 14 and on 28 it really fly's.
This is on an OUYA

@lubomyr

Whats the speed options doing in relation to the CPU / CHIPSET timeslice.
As this will effect game speeds and make things run to slow or fast.

[lubomyr]

FOL,
This question too hard for me.
I don't know.

Can you re-enable the option in the menu.
It defaults time slice to 2, which is around 90% CPU to 10% CHIPSET.

Quick look at the source, I can see its in the GP2x menu.

[olesio]

@Higgy: do you tested hdf with Jumping Jack, which I prepared? Because under 28 MHz I got slow speed too. If you have better, you are probable owner of good and fast device :/

[Higgy]

Yes I tested your HDF.
On 14MHz it is ok. That game is difficult.
I am running UAE4ALL2 on an OUYA, so quite reasonable specs. - Quad Core @ 1.7 GHz

[Higgy]

I got Putty Squad running on WinUAE and created a WHDLoad running version, so hopefully get that onto the OUYA and running on UAE4ALL2.

[lubomyr]

liveevil,
1) Sorry, but i can't understand this request
2) I also want, but don't know how to implement it
3) Description is not correct. It my mistake.
4) As i remember libSDL have some hack for more compatibility with Hackers Keyboard. But i don't detected any games which works with hacker keyboard more correct than Multiling O. I confirm some games works only with built-in keyboard.

#if !( defined(PANDORA) || defined(ANDROIDSDL) )
extern int timeslice_mode;
#endif

#if !( defined(PANDORA) || defined(ANDROIDSDL) )
	timeslice_mode = 2;
#endif

As i understand code, timeslice not used anymore

Would have to have another look, when I get chance.
Wonder why its been removed. As it may help with some issues.

People have to remember, FAMEC is not 100% perfect.
So not everything will work with it.

Probably timeslice been implemented with another way

void m68k_release_timeslice(void)
{
	if (m68kcontext.execinfo & M68K_RUNNING)
	{
		cycles_not_done = io_cycle_counter >> mainMenu_CPU_speed;
		io_cycle_counter = 0;
	}
}

[lubomyr]

new version 2.3.4.1

apk: uae4all2-sdl-2.3.4.1.apk

source: uae4all2-src-09012014.tar.gz gui lib source guichan-src-03012014.tar.gz

- added eject buttons for every floppy drives

}

Hmmmm, what about the throttle.
Would need to see the rest of code to workout what release timeslice is doing.

[Higgy]

Throttle - maybe this would help games that run too fast? Oh I wish I went down the electronics/programming route somethings.

[Ariath]

The config manager has a bug: You can write with the vkeyb, but the backspace doesn't work.
Thanks for the eject buttons .

Ser ya!

[lubomyr]

Ariarh,
I tested config manager with different android keyboards and with all - backspace works correct.

[Ariath]

Strange... i'll re-check later, but... i think i use the standard Android keyboard.
BTW, i have Jelly Bean.

See ya!
