PSP Battery Timer (Nyan Cat Theme)

Go Nyan Cat!

Download

This is a PSP homebrew that helps you measure your system's maximum battery life. The brew does this pretty simply by counting up from zero and saving at 5 minute intervals for later recall (while the nyan cat does his thing). When you plug your system back in after the battery expires, the battery life, accurate within 5 minutes, will be recalled for your viewing.

Of course, some people might just want to use this to nyan away all day -- and that's perfectly fine -- maybe it's even recommended!

Features:
--It's got the Nyan Cat!

--Signed. Can be played on any PSP, hacked or not.
--Easy to use, just start it.
--Customizable . Rename any mp3 'song.mp3' (no quotes) and drop it in the 'PSP Battery Timer (nyan!)' folder for custom music. I've provided a mellow tune here as a good counterpoint to the lively 'nyan' theme. (optional song.mp3)
--In fact, you can customize anything in this homebrew, it's Lua. You have everything you need here to make your own signed PSP homebrew! Go to www.retroemu.com for tutorials and help-- it's not as hard as you think to homebrew![/p]

Good work....this is actually one of those things that's handy because you've never really thought about it.

Although given Li-On battery best practice i'd suggest playing down to the blink of the power light rather than to dead.

OMG IT HAS NYAN CAT. MUST GET.

I should see what my batteries are like. I got my PSP used and I haven't really gotten much out of it, it seems the batteries die quickly, anyways.

You should use RemoteJoyLite to record your PSP screen, just saying.

I considered that, but I didn't want to hack my drivers. Is it safe? (win7)

I depend on my computer too much to risk messing it up.

This should be the background music.... shouldn't have changed it

Could you add the ability to test both 222mhz and 333mhz clock speeds?

I believe there is a lua function for that, I'll see if I can add it in.

Awwr, the sound doesn't restart when the PSP comes out of sleep mode.

*This bug is present in the LPE v8 interpreter that I used, I tested a few games and was able to repeat the bug.
The interpreter clears the Mp3 file out of RAM while its in sleep mode for some reason. Start + Select will now reload the song. Nyan!
