Audio is a problem mainly in RK2705 chips.

From my observations it doesnt work well if the external headphones or other type of speaker lack of built-in amplifier. If you plug in the player into speakers with Line-In support then the Audio is as good as normal (I checked it on my Creative 5.1 Speakers). But If I plug the player to any kind of headphones it seems that the signal from the player is too weak so we hear only background phase with lack of "common for both channels" phase (center).

I tried to figure this out long time ago, but with no success. Sometimes (on original firmware) when I plug in the connector the player has this weak signal for about 1 sec, then it turns into full sound. Perhaps there is cyclic functions linked to main() which checks jack-socket regardless RK_SDK original functions - it would explain the delay I've just talked about.

About games... yeah it's pretty long way to achieve such platform.

I assume that now, we can only run some code at boot and thats it. We must create some sort of app menu, where we can execute the code from the menu.

I was experimenting with running my own code months ago, and was able to replace STOPWATCH from my menu with my own piece of simple code. But this was harsh and didnt include executing external file - just patching existing base.rkw

I am currently downloading the package, I'll try to understand how it works exactly, maybe then I will be able to help more.

Just wondering, whether it will be hard to patch firmware the way that we will be able to open files in explorer that are currently unsupported. There is a lot of variables and links to be patched, but it would be cool if we can make new file types supported easily, so appropriate elf will be executed if we CLICK on some file in explorer regarding the file extension.

If that is doable, then a lot of excitement just wait for us ppl :-)
