Random GameBoot Loader v1 For 3.02 OE-A For PSP

Note: a custom opening_plugin.rco will cause a crash if using the psx emu so be aware of this!

First it requires you to flash two files to the right place that flash0 folder path is
To flash you use PSPFiler v2.0
After flashing the two files, one will change the gameboot path to ms0:/seplugins/gboot/
The other file will get rid of the SCE words that will go ontop of gameboots if not flashed.

Now the fun part
Download and store gameboot pmf files into gboot
Please don't store random files there because I did not do a good file type checking
Enable the randomgameboot in the recovery plugins of 3.02OE for vshex
Now it should choose a random gameboot each time it goes to vshex.

It will also choose the same gameboot sometimes

This might be buggy because I really don't know c that well to do file handling stuff

NOTE: FLASHING THE OPENING_PLUGIN.RCO WILL makes ps1 games not work.

Not too big of a hack, but a hack nonetheless.

If you're like me, you'll want to customize every last bit of all your firmwares (flash, devhook, etc) Well, you've probably stumbled across the 01-12.bmp and tried editing to find that not all the images loaded. Well, I took a bit of time and figured out that Sony simply merged all the images into one file. You cna do this just the same way by simply opening up a new file in a hex editor, then opening each image you want to use in the hex editor and copying the code and pasting them right after the last one in the order you want them. Its very simple stuff. Heres my BG set I made, try it out if you want:

http://www.sendspace.com/file/iqbovt

replace that with ms0:\dh\301\f0\vsh\resource\01-12.bmp

So theres an easy way and a hard way, well actually, there's an easy way, and an even easier way.

To Do it manually:
- Download a hex editor, there's plenty of free ones out there for every operating system.
- Open a new file in the hex editor
- Open the images you want to use (01.bmp 02.bmp 03.bmp 04.bmp 05.bmp 06.bmp 07.bmp 08.bmp 09.bmp 10.bmp 11.bmp 12.bmp)
- Select the entire code for 01.bmp (Ctrl + A in windows should select all)
- Copy it and paste it into the new blank file
- Now you can close 01.bmp and go to 02.bmp
- Copy all the code for 02.bmp and paste all tis code right after the code you pasted for 01.bmp, dont put any space or anything between them, jus thte image right after the last one.
- Repeat the steps for all the images and save as "01-12.bmp"
- Check the file size should be 72.3kb (74,112bytes)
- Copy it to ms0:\dh\301\f0\vsh\resource\01-12.bmp and overwrite the old one
- Load devhook and see if it worked
- Enjoy!

I've made a little BATCH file for windows users to use and it'll easily merge the images for you.

Instructions for the Merger:
- Place the BMP Merger.bat in the same folder as the 01.bmp 02.bmp 03.bmp 04.bmp 05.bmp 06.bmp 07.bmp 08.bmp 09.bmp 10.bmp 11.bmp and 12.bmp
- Run BMP Merger.bat
- You will now have a 01-12.bmp, put it in ms0:\dh\301\f0\vsh\resource\01-12.bmp and overwright the old one

v0.7 - (beta than ever)

# Fixed a dynarec bug involving flags generating functions in
contiguous conditional blocks. Fixes music in Super Mario
Advance 2-4.
# Fixed a dynarec bug where Thumb mov imm instructions wouldn't
set flags. Fixes Zelda: Minish Cap, Megaman Battle Network,
probably others. Comes at a slight speed cost.
# Fixed a MIPS dynarec bug where some delay slots might not
get filled rarely, causing chaos. Don't know if it improves
any games.
# Improved self-modifying code detection. Makes Golden Sun,
Golden Sun 2, and Madden 2007 sorta work but excrutiatingly
slowly. Looking for a game-specific workaround for this - if you
want to play these games you'll have to wait for now
# Fixed a bug causing the interrupt disable flag to go down
when SWIs are entered, causing crashes/resets. Fixes
Super Mario Advance 2-4.
# Fixed menu crashing when strings with certain characters are
printed (for instance going to the menu after loading the
BIOS)
# Accidentally forgot to render win0 + win1 + objwin when all
active at the same time, many weeks ago. Added that, should fix
some parts in games that had frozen screens.
# Fixed some issues with gpsp.cfg needing to be present and
corrupting, hopefully. At the very least sanity checks are
performed on the config file.
# Made it so assigning the frameskip button to something besides
triangle actually worked as expected.
# Fixed ability to restart current game if nothing is loaded
(ie, crash)
# Added interrupt on cpsr modification support to the dynarec
(fixes backgrounds in Castlevania: Harmony of Dissonance)
# Added open addressing for ldm/stm instructions (fixes
Super Mario Advance 3)
# Improved cycle accuracy a little. Don't know of anything this
fixes, but games with idle loops will run a little better w/o
idle loop elimination (but should still be added when possible)
# Fixed some bugs causing sound to play sometimes when it shouldn't.
@ Added dead flag elimination for Thumb code. May possibly have
noticeable performance increases (Thumb emited coded size can
have a reduction of 20% or more)
@ Added code generation for divide SWI. May have a small speed
increase in some games.
+ Added analog nub support (special thanks to psp298 for the
code)
+ Added fractional frameskip. Go below 0 to get them. A frameskip
of 1/2 for instance means render 2 out of every 3 frames, 2/3
means render 3 out of every 4 frames, etc. Possibly useful for
games that are not quite fast enough at fs0 but fullspeed at
fs1...
