What this extender does ---------------------------------------------------------------------:

+ Pads with the rom with 0x01's to 24MB.
+ Decompresses all MIO0 files (with proper alignment) to 0x800000, with 32KB gaps after each file.
+ Remaps all of the pointers to these files in the level scripts (and one asm pointer)
+ Changes all 0x18 commands to 0x17 commands in the level scripts
+ Modifies the 0x1A command's asm routine to load raw files instead of MIO0 data
+ Replaces the segment 0x02 MIO0 loader with a raw file loader
+ Removes the main CRC check and replaces the CRC string with 0xFF's (optional)
+ Adds 'EXT2' to the image name
+ Resurrects the missing character textures from the Japanese rom to the end of segment 0x02 (Pics: http://imgur.com/1firmgd,zdT4VHZ)

To use it, either drag your rom onto the exe or drag your rom into the exe's window and press enter.
Like VL-Tone's extender, this uses BGNG's mio0dec.exe, but I've linked it into AltExtender's exe to make it more portable.
mio0dec.exe and and a directory "mio0_temp" are created temporarily while the rom is being decompressed.

What's different in this extender -----------------------------------------------------------:

+ This extender decompresses all MIO0 files to aligned addresses, meaning increased emulator support and support for real N64 consoles
+ With the edited 0x1A command, and replaced 0x02 segment loader, none of the decompressed files need 'fake' MIO0 headers

This extender makes the following assembly edits --------------------------------------------:

If you opted to do the remove the main CRC check:
@ 0000066C: NOP  // Ignore final CRC1 comparison
@ 00000678: NOP  // Ignore final CRC2 comparison

LUI A1, 0x0080
ORI A1, A1, 0x0000
LUI A2, 0x0081
ORI A2, A2, 0xA20C
JAL 0x8027868C
