I recently upgraded from a Clip+ to a Clip Zip and have noticed issues with Rockboy.

[Issues]

-Severe framerate issues, requires high frame-skipping.
-Maintain Ratio Screen Scaling crashes when rotating.

[Tested On]

-Metroid 2

saratoga:
The first is due to the slow CPU most likely.  The second sounds like a bug, so you should file a report on the bug tracker (link on the left side of your screen).

ImpTaimer:
I cannot post on the bug tracker because it requires and additional account / keeps telling me "That user does not exist on this Flyspray installation".

Feels a bit unnecessary to create an additional account just to file a bug report, assuming that's what I need to do and it's not an issue with my web browser (Firefox with Script and Add blocker).

If necessary I will do so, but I'd rather not.

Llorean:
Yes it requires an additional account.

bertrik:
The CPU in the clip zip isn't *that* slow, it's faster than a lot of ipods. Another thing that requires a lot of time is the display update. Display updates are done over a 1-bit (SPI) interface. The SPI interface currently runs at only 6 MHz so a full screen update takes 96x96x16 / 6 MHz = 24.6 ms (or about 40 Hz max).

The clip+ has fewer pixels and those pixels only take 1 bit each vs. 16 bits for the clip zip, so for the clip+ the impact of the screen updates is a lot lower.
