Attack of the Mutants 0.4a - Modpack Edition / 7th November 2005

Changes-This released is packed with many great player made mods
-Added a temporary fix to load and play large mp3's that would previously crashed the game
-MP3's will now also play from within folders in "/psp/music"
-Fixed a bug where a folder property could be inadvertently set when compressing up a mod, hiding it from the mod list. (Thanks xxxdvlman)
-If NintendoDSMouth.png is a blank all teal file, a black rectangle will not be drawn on the Boss either
-If mp3 play is not enabled and a mod is loaded with no custom music, default AOTM music will reload
-A few other small bug fixes

NOTE: 1.0 users need to copy the "Mods" and "Sounds" folder out of the 1.5 AOTM to their 1.0 eboot folder.

For this release, I converted many of the included mods graphics to an indexed color system, making sure there was no quality loss from the original. This significantly reduces the total size of the Modpack, bringing the download to about 4 meg, and the install to about 8 meg

I want to give a big thanks to all the mod authors for making all these awesome mods!

I've been busy working on my other project lately, so I only got a few small fixes in the core game, but I do still plan on working more on this after the other project smooths out =)

Space Invadors Atom Mod by Squee-D 29th October 2005

Most of you are probably too young to remember, but Space Invaders had a colour backdrop just like in the MOD. But it sure wasn't on the screen. They had a printed cardboard backdrop with a piece of glass in front of it at an angle, the glass reflected the monitor image giving you the overlay effect. In fact, there was no CPU in Space Invaders, IIRC it was all discrete logic chips.

So from one cutting edge technology to another...

Heres the early version of my Space Invaders mod.

None of the animated sprites are done yet, and I got lazy with the level texts :) Other than that though – brand new Main, Background, Pause and Game Over Screens. New sprites in wonderful monochrome! yay!

Duck Hunt Extreme 23rd october 2005 by JoJaSc (Mod of Aotm)

Super Metroid Mod 21st October 2005 by Arko

I made some new graphics for Super Metroid fans.

I did it just for fun and didn't expect anything great from it - but although its not finished yet i think its quite funny.

just unzip the graphics into your AOTM directory, thats all.
(for example H:\psp\game\aotm)

I also tried to make some screenshots, but thats not easy... the big boss killed me everytime before i could take a good picture =)

... so you have to go for it yourselves!

Star wars Mod 21st October 2005 by Jdemon

Ok here are my "beta" mods They are "Star Wars" themed. Just overwrite the folders to your gamecard. I think I did the 1.0 right but have no way of checking it since I have a 1.5....anyone?

I'm saying "beta" because I do intend to finish it of with some other sounds.

This is alot of fun DeNitro... once again thanks for sharing with the community. Is there any way you can make it so it saves your options? Oh and one other about some points for all the small asteroids you blow up?

SEC - Saturn Expedition Committee -

Big thanks to KiLLeR - X for getting homebrew running on the 1.5's

I havn't changed over to the PSPSDK yet cause I didn't have much time to port the code and test.
I have looked at it though and it's amazing. Thank you ps2dev team for the incredible work.
With that it would be possible to do more then just move simple sprites around =P

Also thanks to the Homebrew community in general for all the donated time
to figure all this stuff out =)
