Hi all! This thread was the occasion for me to start a battery mod for my gp2x. I decided to go with the folowing Polymer Lithium Ion Batteries : http://www.sparkfun.com/commerce/product_info.php?products_id=8484 My gp2x first edition never had a good battery life, even with good cell, I only...

Current version of gngeo have this option, next one should also support it. I still think the best option is to use the universal bios anyway. While I'm waiting for my pandora, if a dev want to try a quick port, a new devel version of gngeo is available via mercurial...

I really don't care about small finish issue. I'd say go for it! Unfortunatly, I don't think I'm in the firt 500.

Thanks Notaz, nice to see a port. I don't have much time to work on gngeo for now unfortunatly. As for the bug with my code and cyclone, it waw IIRC with the lastest svn source of gngeo, not the 0.7. Or maybe it was my toolchain... I dunno

nice! :) gngb is actually an old project of my brother. I've write the sound part and the frameskip code however. I'm happy to see that it work ok on wiz, on the gp2x it was too slow. gngb should have a good compatibility but is not as optimized as gnuboy. Is it fullspeed?

I'm working on it.

and this built in program prove that the menu sucks big time :o The touchscreen works very well in the test mode whereas it's unusable in the menu.

Strange, the cyclone core work without any problem on other arm platform. Maybe some kind of regression with the cortex? QUOTE For pepone : It was not the scale2x effect, but scale x 2 like you tought. With the scale2x effect, 22khz sound and 500mhz Cpu we get 54 average fps on twinkle...

At first I've readed Scale2x blitter, that's what impressed me, but maybe it's only a scale by 2? This scaling is in software in gngeo and not optimized though.

And for fun : Metal Slug X @ 800mhz without "scale 2x" and "scanline 50%" effects : ~146 fps Wow :blink: With sound on?

nice! but you really shouldn't release gngeo with a neogeo bios included ;)

I've got also a günter one:

Yes it is!

The only obstacle to port chrome could have been the v8 javascript engine, because it use just in time compilation. But since v8 support also arm cpu, a port is indeed possible.

Great! I was a little disappointed with the button response of the JXD301 to be honest.
