Lightbulb IMGFSFromDump-TURBO v2.4.0 with file prefetching and multicore compression (19/09/10)

Yes, it's actually just as awesome as it sounds: multicore-multithreaded compression allows it to compress up to 2x faster on dualcores and 4x faster on quadcores but it's not just that, it also does realtime file prefetching while compressing, allowing imgfs to be built much faster even on singlecore machines and without causing any additional hard-drive overhead. The v2.2.2 version also allows selecting the compression (LZX/XPR/None) trough a command switch, overriding the compression setting dictated by the source imgfs file and finally removing the need of having to hexedit the original imgfs file to change compression type.

Remember to fasten your seat belts and turn off any electronic gadget, it's so fast your PC chassis could actually take off!

And remember, *use this at your own risk* I don't take responsibilities, especially if your computer chassis really takes off .

Command line syntax
ImgfsFromDump.exe [-compression <LZX/XPR/None>] [-freespace <NumberOfMegaBytes>] [-empty] [-verbose] <imgfs-in.bin> <imgfs-out.bin>

All parameters but the input and output file are optional so you can use the tool in ervius' and other kitchens without having any issue just by replacing the imgfsfromdump.exe file.

NOTE: Oskitchen already comes with customized versions of this tool so please do not replace the one oskitchen comes with.

Version 2.1: faster and uses less ram

Version 2.2.2 version: allows selection of compression (also allows building ROMs with no compression and removes the 256mb IMGFS file size limit)

Version 2.2.3 version: compiled statically so it doesn't need any c++ runtime to work

Version 2.3.0 version: now more stable, no more hanging with None compression (I had it running in batch mode for days and it never gave an issue with it or other compressions), allows setting the free space (if you manage to use imageupdate) and allows creating empty imgfs.bin without requiring a dump folder (useful for reducing payloads)

(NEW!) Version 2.4.0TEST: implemented native support for unicode file names (used in stock Oboe ROMs).

Flashing with the new imgfsfromdump. I went from 1 minute and 3 seconds for a LZX compression to just 21.45 seconds. I did have to use a different cecompr_nt.dll then the one you supplied for lzx compression to work, but other than that, nice work!

cecompr_nt.dll in the zip file support both LZX and XPR compression or not?

It shouldn't since it's an old version, just overwrite it with a more recent one.
