   * Allow browsing the entire filesystem for ROMs.
That could already be done with the previous version by Notepad-editing gpsp_romdir and putting only a "\" in it :P

Sorry for double posting but I found a bug with the new version, and it only happened once for now.
I used the savestate feature to save in the state 0 and then the miniclock from nClock appeared on top of the screen ???
I pressed "menu" to see if it would make it go and it did. And now saving and loading work perfectly.

Hayleia, I'm not sure exactly how nClock works, so I can't really help there.

Also, official video:

I'm getting some screen flashes, where it's off by a good number of pixels (like, a third of the screen) for one frame.  Using unblended scaling.
I'll see if I can get it to happen again, it was happening during menus...

Yeah, that seems to happen for a single frame soon after starting a game. I haven't figured out what causes it.

Congratulations calc84maniac for the ticalc.org release.
http://www.ticalc.org/archives/files/fileinfo/449/44971.html

In the readme, you mention "set LCD speed to 60Hz to improve overall timing".

What's was the default speed and how did you change it?

Nice video calc84maniac. The only issue is that we don't see the calc borders due to the screen brightness, so get prepared for "fake" Youtube comments. D:

I did the same thing for gbc4nspire a while back. The normal speed is around 57-58Hz, so I changed the LCD timing registers to make it a little faster. I think I just changed the Horizontal Front Porch value to 26 (and I forget what the original value is, since I restore it by reading it beforehand rather than using a hardcoded value)

Edit: According to my code comments in gbc4nspire, it's normally 49.

Will the 60 Hz limit cause issues with european/PAL games that are 50 Hz? Or is it different for handheld devices?

All GBAs worldwide are the exact same hardware (since they don't have to connect to a TV)

not the dust game, the roguelike.

zincland.com/powder

@Calc84maniac another bonus because of that is that Handhelds are almost always region-free, so you can import european and japanese games for your US handheld with no issues.

POWDER is one of my favorite games. I first found it while looking for GBA homebrew for my flashcart, and I still regularly play the DS version.
