I guess ill give step by step for the flash 1 thing im talkin about:
1. get the fontmod folder, birdman font mod, fix reg3.
2. next change name of fontmod folder to font and put it on the psp root.
3. Put a font from birdman package in the font folder.
4. Run filer and copy the registry folder to the root of you psp.
5. Next open the system.dreg file on hex editor.
6. Change flash0:/font to flash1:/font.
7. Save system.dreg file.
8. Copy system.dreg and system.ireg to the fix reg folder.
9. Run fix reg.
10. Copy the files back to the registry folder.
11. Run filer.
12. Copy the font folder to the flash1 FIRST!!!
13. Copy the registry folder to the flash1.
14. Close filer. reboot psp.
*Note: With the font in the flash1 you dont have to worry about taking out your ms.
**Note: This will not end up in bsod like high memory mem cards that take awhile to load and usually if not always end in bsod.
