=================================
==== ABOUT PROJECT BASE:

Project Base is a Super Metroid mod (“ROM hack”) with smoother mechanics, extensive level edits, graphical touch-ups, programming changes, new content, and much more. It can be played on Snes9x, higan/BSNES, ZSNES, repro carts, SD2SNES, SNES Classic Mini, and probably anything else that is able to load Super Nintendo games.

The difficulty level of Project Base is roughly the same as Super Metroid's difficulty level, which means that completing the game does NOT require any glitches or advanced techniques (not even walljumps). The current release is stable and fully playable.

"Vanilla" leaves Super Metroid's engine/movement completely untouched. It has no extra code features or special colors, and only the map is changed.

If you don't like spoilers, you should play it now before reading any more information about it.

Don't know how to play it? The easiest way is to download a SNES emulator, open the emulator, and then open the Project Base .SMC file in the emulator. Wanna play it with a controller or your SNES console? SD2SNES (more expensive) and repro carts (less expensive) are good options. For emulators, most USB controllers will work.



=================================
==== IMAGERY
Project Base-related graphic edits and logo artwork.



=================================
==== OLD VERSIONS
See how far we've come, and wonder how far we've yet to go.



=================================
==== CONFIG PATCHES
Old and mostly obsolete. Use at your own risk.
Can be applied to vanilla Super Metroid and most hacks.

SPECIAL THANKS:
The PB speedrunning community has clocked countless hours streaming, routing, finding bugs, and promoting the game. Future versions will be much more polished because of your work.

Charity marathons that feature Project Base are great. Hopefully ROM hacks as a donation incentive will keep gaining momentum.

suku for creating Vanilla++, which inspired me to create the first version of PB

AdvancedPillow for the Project Base and Hollow Eve/B2-TW cartridge sets!

And THANK YOU to everybody else who takes their time to play PB, mention it to others, report bugs, post opinions, and do things.

- [harmless?] Practice HUD has graphical errors after loading a saved game in Tourian

- [harmless] Item collection percentage isn't accurate; the actual maximum is curreently 108%
- [harmless] Title screen year still says 2020; can't modify without significant code changes
- [harmless] Unable to run across frozen buyons (fixed via level design rework)
- [harmless] Occasional slightly glitchy Samus gfx when entering doors (going right only?)
- [harmless] Save stations occasionally misplace samus by 1 or 2 tiles
