 *   Wrote PS1 Packer and released it as an easy to use [submodule](https://github.com/pcsx-redux/support). Helped implement it for the memory card boot methods.
 
+*   Corrected the CD_REGS value in `loader/cdrom.c` to use the right memory region.
+
+*   Came up with the best `cdrom:\\` text stripper for `CdGetLbn()` in `loader/secondary.c`

 	King's Field Japan (SLPS_00017) is a very early PSX.EXE Japan game. While the PSX.EXE is having 0x34/0x38 contain SP values, these are apparently garbage and not being used in reality by a real BIOS boot. These ARE being used by both our exec calls below however so we need to zero out that garbage so it is not used, which finally allows King's Feild (and most likely other PSX.EXE games) to boot correctly.
