SETUP:

- You can press F1 in this game to toggle rastereffects and speedup gameplay.


Bugs:

WIP:

- 0.99u3: Pierpaolo Prazzoli removed a speedup kludge in the M92 video driver. This fixed R-Type Leo video.

- 0.80u2: R. Belmont added channel status readback to the IREM GA-20 PCM sound, which fixes some occasional odd voice-stealing behavior I've heard playing R-Type Leo. Please enjoy R-Type Leo LOUDLY now.

- 0.60: Added R-Type Leo (World rev. C). Changed 'R-Type Leo (Japan)' to clone 'R-Type Leo (Japan rev. D)'. Renamed (rtypeleo) to (rtypelej).

- 0.55: Changed V30 CPU2 from flags audio to normal V30.

- 0.53: Bryan McPhail and Nicola Salmoria decrypted the sound CPU in Gunforce, Blade Master, Lethal Thunder, Undercover Cops, Mystic Riders, Major Title 2, Hook, R-Type Leo, In the Hunt and Perfect Soldiers.

- 25th July 2001: Nicola Salmoria improved the IREM sound CPU emulation, which allows R-Type Leo to work without kludges, and he decrypted Hook and Mystic Riders.

- 24th July 2001: Nicola Salmoria yet improved the IREM CPU decryption tables, and got sound working in Undercover Cops and R-Type Leo.

- 0.37b8: Added V30 (14318180 Hz) CPU2, YM2151 and GA20 with 3579545 Hz.

- 11th September 2000: Bryan McPhail sent in a huge Irem games update with a rewritten NEC core, fixing many bugs. R-Type Leo title screen was fixed as well as preliminary Irem GA20 custom sample player support was added.

- 0.36b15: Added dipswitches 'Difficulty', 'Allow Continue' and 'Demo Sounds'.

- 0.36b11: Changed description to 'R-Type Leo (Japan)'.

- 0.36b10: Changed description to 'R-Type Leo input_ports_(Japan)'.

- 11th November 1999: Bryan McPhail speeded up R-Type Leo.

- 30th September 1999: Bryan McPhail fixed R-Type Leo from crashing at later levels.

- 0.36b6: Bryan McPhail added 'R-Type Leo (Japan)' (Irem 1992). Known issues: Title screen is incorrect, it uses mask sprites but I can't find how the effect is turned on/off. Colour flicker on level 2. Crashes after continue screen (related to memcard?). Crash after level 3?

- 24th September 1999: Oliver Bergmann sent in a NEC V20, V30, V33 cpu core, and Bryan McPhail submitted an Irem M92 driver with support for Blade Master, Gunforce, Lethal Thunder, Hook, Undercover Cops, R-type Leo, Major Title 2 and In The Hunt, but none of the games have sound because of an encrypted sound CPU.

History


Arcade Video game published 27 years ago:

R*Type Leo (c) 1992 Irem.

R-Type Leo is a horizontally-scrolling shoot-em-up and is the third and final arcade release of this classic series (although numerous console-only sequels would follow, see 'Series' for details).

Mankind are currently at peace with their former adversaries, the Bydo Empire, and have taken the opportunity to undertake a massive project called 'Project Paradise'. This involved the construction of an artificial terrestrial-like planet called 'Eden', created as a safe haven should humanity once again find itself under threat. However, soon after construction is completed, 'Major' - the bio-computer system responsible for maintaining Eden - malfunctions, taking control of the planet's defences and launching an attack on mankind. It is up to the newly-developed 'R-9 Leo' fleet to fly in and stop Major's assault on its creators.

R-Type Leo deviates from the gameplay style of its predecessors by removing the use of both the 'Force Pod' and the 'Wave Cannon'. The new weapons are called 'Force Bits' (later identified in "R-Type Final" as "Psy Bits") and the 'Bit Shot'. The three 'Force Bit' weapon types are:
* Red - Claw Laser: a powerful horizontal laser beam and horizontal traverse wave
* Blue - Mirror Laser: fires multiple, ricocheting lasers.
* Green - Search Laser LRG: fires semi-homing lasers that can bend at 90 degree angles.

Unlike previous 'Bit' devices, the 'Force/Psy Bits' are capable of firing either forwards or backwards (their direction dictated by the movement of the ship itself). Finally, the 'Wave Cannon' is replaced by a 'Bit Shot', in which the Psy Bits detach from the ship and collide with the nearest enemy. The Bits can only do this for a limited time before running out of energy, and must be recalled to the ship to recharge.

R Type Leo consists of 6 stages and is the first game in the series to allow 2 players to play simultaneously.

R*Type Leo was developed by Irem's internal group, 'Nanao' (authors of the famous "Meikyuu Jima"); the original authors of R*Type's series moved to 'Aicom' (bought by SNK) and went on to develop another superb shoot-em-up, "Pulstar"; released in 1995.
