Cosmic Commuter - PAL50Hz Conversion Hack V1.1 (Atari 2600) Romhack

Well, This game Was never released in true PAL 50Hz speed release and was a NTSC only exclusive release. (Until now)

This has got to be the most well worked on Hack conversion of Activision’s Cosmic Commuter.
A horizontal shooter-gamer Your mission is to shoot obstacles, grabbing fuel. and grabbing people Once you saved all the people. You can take off to another planet/Level

This hack of mine has not only been having the colour palette change to show the correct colours when playing on a PAL Atari 2600 console. This now can happily run in PAL 50Hz speed and in PAL 50fps refresh rate.

This is without a doubt the brand new fully PAL version converted Atari 2600 Game.

Spend hours to work out the Stella Debugger to adjust the values for it.
on Developer mode on Stella. it shows the fps spot on at 50.0fps with 312 scanlines ( PAL Atari 2600 standard )

Maybe one day I might updated one day once I can work out how to optimise the gameplay.
Can’t guarantee it as most PAL Activision Games for the Atari 2600 did run slower. But I’m cool with it. 🙂 I guess
“Slow and steady ins the race? LOL”

Game works wonders on any emulator (Especially Stella)
This game will work on original Atari 2600 Hardware (4-switcher, 6 switch & Atari 2600 Jr ) using the harmony cartridge.
Confirmed to work on the 2600+ with correct colours and displaying at 50Hz (50.0fps) Refresh rate
