- TIPS AND TRICKS -

* Hint 1 - The Small Demons Change Their Shapes Three Times : The first demon shape (Demoneye-jr : 40 pts) turns into the second (Octoplus : 70 pts) and the second into the third (Octobomb : 100 pts) when they are shot. Care must be taken to prevent Octobomb ramming into the spaceship.

* Hint 2 - Bonus Chance for 3-Demon Formation : Sometimes Demoneye-jr and Octoplus change their color. If Octoplus are shot while their color is changing they will turn into a group of three Octobombs. If all these three demons are killed a bonus point is scored.

* Hint 3 - Aim At The Heart Of he Super-Demon : When all the small demons have been wiped out, a hole appears beneath the body of the Super-Demon (Demoneye-X : 500 pts). This is the Super-Demon's weak point. If the player can shoot the Super-Demon in the heart he can destroy the creature.

* Hint 4 - 3-Eyes Demon King Appears : If the player succeeds in a series of two games, a three-eyed demon king appears (Demoneye-King : 1500 pts). To destroy it, the player must hit its heart 3 times with his missiles.

MAME Info:

0.74u2 [Pierpaolo Prazzoli]

Bugs:

- 32bit build has "stronger" colors. Firewave (ID 03324)

WIP:

- 0.122u7: Rewrote and modernized the redalert driver [Zsolt Vasvari]: Correct colors, in places different from the manual's description, but matches the flyer perfectly. Added speech. Fixed AY-8910 sounds. Odds and ends. Corrected colors in Demoneye-X. Added some sound to Demoneye-X. Marked Demoneye-X it NOT_WORKING, due to the (still) missing 3rd gfx layer that makes it impossible to pass the 2nd level. Fixed cpu2 rom address to $3000. Changed user1 rom ($200) to proms ($0 - color). Changed M6502 CPU1 clock speed to 781250 Hz, M6802 CPU2 to 894886 Hz and 2x AY-3-8910A to 1789772 Hz.

- 0.74u2: Pierpaolo Prazzoli added Demoneye-X (Irem 1981). GFX problems and no sound.

- 1st October 2003: Pierpaolo Prazzoli added Demoneye-X to the Red Alert driver (it's missing sound and has wrong colors).
