- Credit during demonstration play causes graphic error. Tafoid (ID 03799)


- 0.145u7: Small Juno First cleanup [Miodrag Milanovic].

- 0.144u7: Kanikani updated Juno First dipswitches. Changed 'Unknown' dipswitch to 'Unused'.

- 31st October 2011: Mr. Do - We have Juno First. Scanned and cleaned by Mikonos from Zona Arcade.

- 0.143u8: Angelo Salese and Chris Hardy fixed Juno First refresh rate to 60Hz and interrupt firing.

- 0.140u2: Atari Ace take some driver_device classes of junofrst/pooyan/rallyx/rocnrope/timeplt/tutankhm (common code in audio/timeplt.c) that cover multiple drivers and split them so that each driver gets their own driver_device class. In most cases, these drivers got entangled because of audio/mcu code that was shared between multiple drivers. Added 'Time Pilot Audio' sound.

- 17th September 2010: Smitdogg - I got a dead Juno First board (cheap) that had some roms labeled differently from the sets in MAME so it looked like an undumped rev but matched one in MAME.

- 0.135u3: Fabio Priuli added common driver data struct to Juno First (as a side effect, we now have save states in Juno First).

- 0.133u1: Renamed (junofstg) to (junofrstg).

- 0.122u6: Changed I8039 CPU3 clock speed to 8MHz.

- 0.120u4: Chris Hardy fixed problems introduced when the Juno First blitter code (video\tutankhm.c) was simplified.

- 0.37b2: Added clone Juno First (Gottlieb).

- 9th April 2000: Matt Osborn dumped Juno First (Gottlieb).

- 0.35b1: Nicola Salmoria fixed shoot sound in Juno First. Changed Z80 CPU2 clock speed to 1789750 Hz.

- 0.34b7: Nicola Salmoria added some more sound effects to Juno First. The shoot sound is still missing. Added I8039 CPU3 and 1x DAC sound.

- 0.33b3: Chris Hardy added Juno First (Konami 1983).
