[MSX] Mappy by Namco LTD & Bug-Byte Software - Gameplay *after* reset - YouTube FiXato

This is a game from my childhood, the MSX tape version of Namco LTD's "Mappy", published by Bug-Byte Software and the Argus Press Software Group. More information about the game, and this release in particular, can be found on Generation MSX(¹) Since I played this mostly on our Philips NMS 8250 MSX2 homecomputer (²), I set the openMSX emulator (³) to emulate this machine, even though the game officially only has an MSX1 version. This video shows how the bells are missing in rounds 5 and 6 if you have reset your MSX after loading the game. Not quite sure what causes this, perhaps the MSX bootup sequence changes or resets something in RAM at the address where the bells are controlled. If you know the exact cause, feel free to leave a comment. Whatever it is, it does make the game slightly harder. It's something I noticed years ago, and as I'm not sure how common knowledge this 'feature' is, I had to create a recording to share this. This video is related to http://www.youtube.com/watch/?v=ttfp7... in which I show where these bells are supposed to be, in the regular gameplay before I reset the MSX system, and http://www.youtube.com/watch/?v=rY99q... which shows the boot and tape loading sequence. There's also a short, combined, comparison video with text annotations available at https://www.youtube.com/watch?v=nhqc9... If you feel like playing an unofficial version of Mappy with enhanced graphics for the MSX2, visit http://www.tiny-yarou.com/kaizoumsx_m... or read more about it on http://www.msx.org/forum/msx-talk/sof... or watch the gameplay footage by Tiny Yarou on https://www.youtube.com/watch?v=EV3l9... This gameplay run makes use of the 'reverse' functionality of the openMSX emulator, which allows me to reverse mistakes. It was recorded using the official stable release of version 0.10.1 of openMSX for Mac OS X. Daily development builds for Windows and Dingux (and soon hopefully Mac OS X and Android again) are available at http://openmsx.fixato.net ¹) "Mappy" on Generation MSX: http://www.generation-msx.nl/software... ²) MSX2, Philips NMS 8250 Wikipedia article: https://en.wikipedia.org/wiki/NMS-8250 ³) openMSX Emulator, official website: http://openmsx.sf.net
