Here's five different versions of the ColecoVision BIOS:

1. Original (has the sometimes excruciatingly long ~12 second title screen on Coleco games)
2. Alternate font (I've never tried this version)
3. Intro skip (completely and automatically skips the 12 second title screen)
4. Fire button skip intro - made famous by doubledown (bypasses the 12 second title screen when you press a fire button)
5. Short title screen - my version (about 3 seconds instead of 12 seconds)

Enjoy,
