Sjaffe, what version firmware do you have? If 4.x, it will only work with version 4 firmware. Version 4 has a different chip altogether. Some more details can be found at Rockbox support site. There is actually a version of Rockbox in development for the m2xx players, although not usable presently. Maybe some day.
I have a 2.x and two 4.x m250’s. I tend to use the 4.x for larger files (many of mine are 3 hours or so), because the FF is accelerated, although the algorithm used is screwy. It barely accelerates and then when it starts to kick in it goes ballistic very quickly! If I turn off my m250s, and later turn them on, play will continue where I left off. However, 95% of the time, if the player turns off because of the battery running down (I use NiMH), the player reverts to the previous memory state (doesn’t recall what file was playing when the battery died or where it was in the file). This is, of course, a major annoyance. On rare occasions it does remember even when the battery died, and I have no idea why.
The 2.x player evidently does not support accelerated FF, so I don’t use it as often. However, I find that the maximum volume on the 2.x player is much greater, which is a major plus for me because I’m using very low efficiency earbuds (Etymotics ER4S). For this reason, the much more efficient ER4P’s are on my shopping list.
I have occasionally had problems with certain large MP3s when employing FF/REW. One file wouldn’t play beyond a certain point and with a few others, the player would go to the beginning of the file suddenly. I guess these players ostensibly support A<–>B repeat between points you set in the file. I haven’t played with that feature.
Note that there is a setting in the firmware for turning on advanced features. The Stopwatch function was totally absent from at least one of my players until I accessed that function. After once having accessed it, the Stopwatch function is there even when advanced features are not turned on. The firmware is a little screwy, obviously.
FYI:
Rockbox m2xx version 4 port
Rockbox m2xx version 2 port
