I might take a look at this, but I'm not promising anything. You need to activate cheat mode and then Alt+F4 should take a screenshot. To activate cheat mode, go to the menu, select Options and type schnosm in the Options menu - your screen will flash white one time.

Change this line (in file jpeg.cpp): memcpy(&pixels[cinfo.output_scanline*row_stride],buffer[0],row_stride); to: memcpy(&pixels[(cinfo.output_scanline-1)*row_stride],buffer[0],row_stride);

Yes, I think that's OK.

The 55 fps with DSP, that's without frame skipping and with fixed parallel working of DSP and CPU, right ?

Good with the OpenGL version. I noticed, that in the DSP version I forgot to implement parallel working of DSP an CPU when SKIP_REFRESH is not defined, but that should be easy to fix if necessary.

Here is the updated code. There's a small speed gain - with less frame skipping (30fps would be fullspeed) the result is now 27.7 fps - still not fullspeed, so it's better to keep current frame skipping. I also fixed a bug in the DSP code, when blitting large alpha surfaces. I also checked...

A bit off-topic, but the ARM9 core was mentioned a few time and it's actually documented - you can find some details in/around this post.

All it needs is a project where the DSP can be used (to run things in parallel), where it actually makes a difference in speed (some of my projects could use this, but they are fast enough without it) and someone to implement it :) I thought about this and it should be pretty simple - I'll...

OK, I'll keep the OpenGL version as it now is. Well, the CPU is working in parallel on frames which won't get displayed, but yes. Currently the CPU is not working in parallel on next displayed frame - that requires a bit more code and I'm kind of tired of the code right now, maybe I'll look at...

So I spent some time (a lot ?) to see if I could get this game running faster on Pandora and here are the results. The game uses SDL surfaces and blitting to render the screen at resolution 780x600, which on Pandora is then scaled down using hw scaler. A small speedup can be gained by using...

I don't know if it was current or earlier change, but when I upgraded my Pandora I noticed a proposed change to configuration file /etc/slim.conf . The proposed change was line: current_theme pnd-default which was changed to current_theme default I'm not sure this was intended...

You can apply this diff to game.c for a small speed increase (about 5% in my testing): Also I wouldn't remove SDL_Delay(...) in the main loop, but replace it with SDL_Delay(0), because currently you are just calling SDL_GetTicks() in a loop.

The adsorption (not absorption) works only in normal mode and boosts your attack power even when your not locked. It lasts a short while and then has to recharge before it can be used again.

I fixed the crash, download the new version on the repo. @Magic Sam: Today I reached my highest sector in normal mode - sector 4. So you are better than me. Have you tried other modes?

@Magic Sam: The bug was caused by an object that should have been created only once at the start, but it was also created after game over (while keeping previous instances). Since the object was involved in drawing, that increased the mount of work with each created object. I can confirm the...

I fixed the bug, download the new version on the repo. I'm not sure about C4A support - there are multiple game modes, you can start at different levels (if you achieved them previously).

Hi, I ported Z-LOCK to Pandora. Z-LOCK is a Japanese shooter with a twist: your shot power is directly proportional to the number of enemies locked on to you. Movement: DPAD / Left nub Shot: [A/Y] Adsorption: [X/B] Pause: [P] Quit: [ESC] Download: repo The source code is inside the PND and...

I tried using GL_OES_draw_texture and it works. You need to use correct coordinate system - the screen coordinate 0,0 is in the bottom left corner. Here is a working simplified example (using EGLPort library):

No, that's the way I intended it to work.

@omega-weapon: Sorry to disappoint. :) @flowen8: I sent you the key.
