I just got the Game Gear out of my dad's loft yesterday, and tested Fantastic Dizzy. I said a while ago I thought the Game Gear version didn't have day/night cycles and can now confirm it doesn't have a night time. It is almost identical to the Master System version except the day/night cycle is non-existant. I also noticed the game flickers a lot on the Game Gear I used, compared to other games. My guess - this is the Master System game with slight modifications to make it run on the Game Gear. The resolution limitation can be seen on this version, and it looks like the sprites were not designed for the Game Gear screen; Dizzy's face and some text such as the damage meter on the rapids isn't very clear, for example. The game runs noticeably faster than my PAL MS version, so I assume all Game Gears including PAL work at 60Hz.
So, in all there isn't much point doing separate GG and MS long plays because they are almost identical. Another related thing - I tried to run Fantastic Dizzy on SMS Plus emulator on the PSP, and managed to get the PAL ".gg" version to work, but it cuts off the bottom 5 or so pixels, and the palette is wrong in a few places, although it runs at full speed. Other Fantastic Dizzy .sms roms don't work at all on any PSP emulators I tried. Dizzy Collection loads the main menu with the wrong palette, and you can hear the sound but pressing start to begin causes a crash.
Another Codemasters game I tried is CJ Elephant Fugitive, and I definitely want to do a longplay of this in the future, as hardly anyone seems to know about it. The sound effects are the same as Fantastic Dizzy in some places, and it is a good game. I'm planning to do a TV-out mod on my Game Gear to record video from it. This will take a while, but I'll post here when it happens.
