Just to be honest, I changed the emulation settings to European Standard - PAL and framerate 50FPS.
Normally I set Color Format to NTSC to play Atari games - not only 2600, but also 5200 and 7800.
The framerates which I CAN use for emulators in general are 50 and 60 frames per second, which correspond to nominal frequency (50/60 Hertz).
Not to nitpick, but wouldn't that give you an unfair advantage playing the game at 5/6th of the normal speed when your emulator setup is capable of running it at normal 100% speed? I know lots of members here have PAL systems and TVs that can only play games at 50 Hertz and that's just fine, but since you've always played all the other games this season at 60 Hertz you kinda made it sound like you intentionally dialed down the speed of this one game and I guess I'm just a little confused at how that wouldn't be a violation of:
CLARIFICATION: No use of cheats, emulation advantages, bugs, cart frying or other variables that would give you an unfair advantage in this HSC. No game enhancements or special favorite settings are allowed for play in the 2600 HSC, unless specifically authorized by your humble yet strict MODERATORS! (Jacob/BAZ.)
I know it's not my job to be the rules police here and that we're supposed to keep the competition fun and friendly, but the way you worded your decision to play this particular game at 50 Hertz just made it sound a little fishy. My apologies if that was not your intention.
