Armv6 Builds

[MaXiMu]

No changes compared with older 0.2 is same github code.
Try without Enable sound emulation
sound enabled very lost perfomance compared with 0.2

[Vincentmrl]

well I have laggy performance with every setting enabled or disabled, and now I can't get past the menu on puzzle bobble.

[BillDoul]

I have the same problem with version 0.3. I hope it can be fixed. Thank you MaXiMu for all your hard hork for us armv6 users.

The menu problem in Puzzle Bobble is a known issue, and I know what the problem is - the game tries to access save/load functionality and I changed that stuff a little. It will be fixed later. In the meantime, you can play Endless mode

is the laggy games problem a known fact in this version,or it's just us armv6 users? The games lag like if they have a not working frameskip even if they got a small speed improvement.

[Henrik]

The sound emulation currently causes a lot of lag, I will fix that for the next release.

well, the fact is: I have the same amount of lag with or without sound, it looks like an armv6 port fault or maybe all phones, probably it's not noticed in armv7 since it's faster, if you want I can make a video (even if it's armv6 it's still the same emu).

You're probably testing games that have broken sound from the start. Some of the games I test are super laggy with sound emulation on, and less laggy with it off.

I tested puzzle bobble and the impossible game WITHOUT AUDIO since 0.2 and now the graphics lag a lot for no reason, this is the problem, sound is unrelated, graphics look like a frameskip of 9-10 frames

I detected now speed up on my armv6 device and works much better

I detected a speedup too, the impossible game now runs perfectly without sound, even if it has small slowdowns when I hold the button. I compared it with the android version and it looks like it's running faster, probably they didn't make a framelimiter yet.

Hey friend, you submit the changes to the git repository?

[Vincentmrl]

ppsspp got updated to 4.0, can you compile it for ARMv6?
I have an idea, can you teach us how to compile it for ARMv6 so we can compile on our own the newer versions?

[Henrik]

I'd like to add official support for ARMv6, so yeah, tell us what you do to make it work

I Only in my compilations for now disable and create for the separate unsupported code native/math/math_utilarmv6.cpp

Code:

#include "math/math_util.h" #include <math.h> #include <stdlib.h> /* static unsigned int randSeed = 22222; // Change this for different random sequences. void SetSeed(unsigned int seed) { randSeed = seed * 382792592; } unsigned int GenerateRandomNumber() { randSeed = (randSeed * 196314165) + 907633515; randSeed ^= _rotl(randSeed, 13); return randSeed; }*/ #include <math.h> #if defined(ARM) void EnableFZ() { int x; asm( # "fmrx %[result],FPSCR \r\n" "orr %[result],%[result],#16777216 \r\n" # "fmxr FPSCR,%[result]" :[result] "=r" (x) : : ); #//printf("ARM FPSCR: %08x\n",x); } void DisableFZ( ) { __asm__ volatile( #"fmrx r0, fpscr\n" //Not supported code by armeabi "bic r0, $(1 << 24)\n" #"fmxr fpscr, r0" : : : "r0"); //Not supported code by armeabi } #else void EnableFZ() { } void DisableFZ() { } #endif

And the Native/android.mk separate TARGET_arch_ABI armeabi /Armeabi-7a and add ARM Mode for the compatibility
