Last year I learned the speedrun of the mobile port, but haven't ended up doing any runs (yet). Nevertheless I did a bunch of research on versions of the game, finding a bunch of them in languages such as German, Russian and Chinese. More recently I took another look and noticed some Chinese versions of GR Mobile that I had missed in the previous research attempt.

The versions are for various devices such as Nokia and Motorola phones. Missions runs at a set screen resolution (depending on version, ranging from 128x128 to 240x320), and it's best to set the emulator to the respective resolution so that the picture is correctly cropped and to reset the game afterwards. GR Mobile exists in several versions for various devices, but the game attempts to correct itself to the screen resolution detected at boot, and device info for this game is scarce, so it's hard to tell which screen resolutions were the intended ones for each version (the existing runs as of now were done at 240x320, but also one of the versions appears to be intended for 176x208 Nokia phones judging by the screen crop, and some versions have smaller title logo graphics probably for 128x160 screens). In addition, note that the smallest versions of Missions remove the Shooting stages, and therefore are not eligible for the currently existing speedrun categories.

The game's rules as of now refer to the resources section for emulator info, presumably pointing to the banned user's resource, which includes the original KEmulator from the late 2000s. However, I personally don't recommend to use it, as there are now better options for emulating J2ME games on PC, which should correctly run this game: FreeJ2ME-Plus, which is open-source, and KEmulator nnmod, which is a modded version of the original KEmulator with accuracy and quality-of-life improvements. (Note that I don't recommend the original "non-plus" FreeJ2ME as it's much less accurate.)

- KEmulator nnmod https://nnproject.cc/kem/ (multi-platform and legacy win32 builds available)

Emulators + GR Mobile/Missions (new)

KEmulator + GR Mobile/Missions

The split trigger for the first split should ideally be upon either unlocking Cliff Farm OR exiting JiggyWiggy's Temple.

As for the level splits, the split trigger would be upon exiting the respective levels.

The last split is timed upon collecting the last required note/jiggy in Spiral Mountain.
