Additional Glitches found.
* Rainbow Prince : Well, the background crash glitch was in stage 2, not 4.
* Story of Lasama(These glitches are not found in standalone dump.)
- 99 lives in start.(Told in Handheld Underground download page.)
- Invincible against enemies. You won't die even you touch enemies! However, you still lose a life.
- When touched by enemies, death sound is looped endlessly until fall to death or clear the stage.
Maybe 'cheat' as copy protection?
These glitches are found both 12 in 1 and 18 in 1.
Also, if Multipack is played in other emulators :
* In BGB, Shi Kong Xing Shou is playable in 12 in 1 and causes Vast Fame's 'Test sram error'. 18 in 1 is not active with message 'bad file size'.
* In VBA, Shi Kong Xing Shou is playable both in 12 in 1 and 18 in 1. However, the emulator will crash soon when you play 18 in 1.
PS.
* I played Zook Z via this multipack. Zook Z is much easier than Zook 2, and difficulty and traps are more complicated than Zook 2. In Zook 2, some traps are VERY annoying.
* This version of Vast Digimon Battle(aka Digimon Ruby in GB) reuses Shui Hu Shen Shou's Music(Told by Shamboozle). This one is much easier than Pokemon Pikecho.
