It looks like this game (US and JP versions) will be available this summer in the Contra Anniversary Collection.
Switch, PS4, XBox One, and Steam will all be valid emulators.

Any runs submitted from these platforms should be marked as emulator and listed in the description as you would list normal PC emulators.  The same emulation rules apply to runs done with the Anniversary Collection version of the game.

**As of 6/12/2019 we are not accepting runs of Probotector, as there have never been any runs submitted so far, and there would need to be an additional set of rules and conversions defined for running at 50hz or 60hz

Genesis Mini runs of this game will also be allowed

MiSTer FPGA runs are allowed since it is probably even more accurate than emulators

Analogue Mega SG runs are allowed, but the game has to under Fully Buffered mode or Single Buffer mode only and display the buffer mode on your run.
runs without display the buffer mode and runs under Zero Delay mode will be rejected.
