the installer deletes LocationFree TV (LFTV) and the Korean font

the installer also deletes “flash0:/dic/apotp.dic” in order to free space for the 1.50 kernel; it’s believed to be the predictive text for Japanese; it isn’t needed for normal operation

if you want to keep these files deleted by the 1.50 installer; do the following:

1. install DC7; use the Format flash options in nand operations menu; make flash1 size around 1MB smaller, make flash3 the smallest possible, and make flash2 a bit smaller (not too much or you won’t be able to download stuff from PlayStation Store); make flash0 as big as possible and continue.
2. install CFW 4.01 M33; update to 5.00 M33.
3. install 1.50 add-on; dump 5.00 using the latest PSARDumper; flash the deleted files you want back.

注意: 1.5版本核心 – 只是供PSP-100X用家使用, PSP-200X(Slim版)並不能用.
