NVFS How-To

[edit] How to get LJP running smoothely on Tungsten E2, T5, T|X, Lifedrive, Treo 650, Treo 680 and other NVFS devices

If you're on a LD (Life Drive), update to ROM version 2.0 (it claims to be for English versions only, but it really works on all LDs. This will allow LJP to notice multiple button presses at once.
Install LJP and ROMS, details at Installation Instructions
Delete background apps that eat Dynamic RAM, like ZLauncher or PicselViewer. Alternatively, move them to card with PowerRun or a similar tool, or use CleanStart to prevent them from loading at reset writing services.
Install UDMH (it's shareware, so'll have to pay 10 bucks or so if you want to use it forever) you usually don't need it on a Treo 680, 755p or Centro. Check the memory info in the upper line of the LJP ROM selector.
Install MemUnfragment (Runs hidden in background after installation) or CleanStart.
Install Imazeki's DBCacheTool. Don't use autoclear. Instead use the DA to clear the RAM right before you launch LJP.
Install DALauncher to access the DA from the command bar.
Do the following: Clear the DBCache. Reset your Palm. Clear the DBCache again. Make sure UDMH is enabled. Run LJP and load a small SNES ROM (such as Super Mario World) to test your setup. SNES needs at least 8 mb of "Max alloc" (as seen by DBCacheTool).
