mouse/keyboard controls should work now

this for more – https://github.com/libretro/Genesis-Plu … 3d52f19c75

HackerBooks is a Python application to download books related to Programming or Computer Sciences. All the books proposed for download are freely available (either creative commons or permissive licenses). Books are organized by title, category, authors.

Changes:

#0.1.6 : released July 6th: Many new books added. Option to download all books at once added in menu (only works if you are online, naturally, and it can take a lot of time, as you can imagine, so only fire it up if you have no time constraint before you).

ptitSeb ported PPSSPP to the OpenPandora handheld. PPSSPP is an open source project, licensed under the GPL 2.0 (or later).

PPSSPP is a PSP emulator written in C++, and translates PSP CPU instructions directly into optimized x86, x64 and (soon) ARM machine code, using an efficient JIT compiler. PPSSPP can thus run on quite low-spec hardware, including stronger Android phones and tablets, as long as there’s support for OpenGL ES 2.0.

Changes:

* In sync with git (v0.8.1 now).
* some new options to play with (like over/underclock virtual CPU/GPU).
