I pondered the same things, then decided:
1) We have E-Loader to load 150 brew. The only notable 1.50 kernel dependent homebrew that E-Loader doesn't want to load is Ressulinski 0.3, and for that you could either use Time Machine, or use Nand Manager to dual boot Custom Firmware
2) Emulators - All mine are working. If your having trouble with one in specific, feel free to PM me
3) I'll try some of the old versions of Auto Start configurator. Maybe one of them will work.
4) Xplora, is cool, but PSP Filer is better anyway IMHO.
5) recovery and satelite offsets are no big deal, and will be found soon. (Actually anyone with a hex editor and some free time could find them...)
6) Blessed Hands Dynamic Editor actually does not need to be updated. Just the bookmarks, and Matchung has already posted updated bookmarks for Dynamic Editor over at EndlessParadigm
Also, you could easily dual boot Custom Firmware, make your theme for 5.00 M33, and use CTF Updater GUI to automatically update the theme to 5.50 GEN-B. (From there only a few manual adjustments needed)
So there is some stuff to think about.
With online play, remote play with PS3, and playstation store unavailable to M33 users, I made the decision to abandon ship, and update to GEN.
GEN also has some nice unique features as well.
- Make Pandora Battery in vsh menu
- Restore Pandora Batteries to normal mode in vsh menu
- Auto launch recovery mode from vsh menu. (Its about 4-5 seconds faster than booting into recovery on m33)
- Hide mac address in vsh
- Custom Firmware blocked games such as Evangilian Joe can ONLY be played on GEN. (M33 or MHU Custom Firmware can not)
- you can have video sub folders with .MP4 files in them and it won't freeze the XMB
- SLIM colors patch for PSP 1000 (FAT model) users. Instead of 12 wallpapers, you can have like 27 tongue.png
I'm not trying to sell anyone on GEN Custom Firmware, simply trying to give some folks a full understanding of their available options.
