Sky Ball is a physics-based small indie game with puzzle elements. It made me think of that very classic and well-crafted balance ball game - Ballance (AKA: 3D Balance Ball) at first glance. Yes, it's actually a beautified and strengthened unofficial clone edition of Ballance. Although Sky Ball is rarely known, it's still worth a try for fans players of Ballance.

MAME32 More! (MAME32M for short) was originally a modified edition of MAME developed by lahow, which joined Kaillera for online gaming support on the basis of MAME Plus!. It not only came with stable netplay similar to MAME32k, but also had many functions from MAME Plus! (like multiple languages support, IPS, etc.). However, the original author of MAME32 More! had stopped developing (he even deleted its homepage). So its final version stopped at 0.84.

For now, it can be regarded as the best (most accurate and comprehensive) unofficial guide for the world's most popular disassembler IDA.
