0.37b6 [Testdriver]


Samples required


WIP:

- 0.138u1: Changed description to 'IPM Invader' and clone (Incomplete Dump) to 'IPM Invader (Incomplete Dump)'.

- 0.133u1: Changed 'I P M Invader (Incomplete Dump)' from a parent set to a clone of 'I P M Invader'. Renamed (ipminva1) to (ipminvad).

- 0.132: Tafoid and Fujix changed year to 1979 (Arcade TV Game List book).

- 0.129u6: Couriersud fixed regression (missing graphics) in 'I P M Invader'.

- 0.128u3: Changed M6502 CPU1 clock speed to 781250 Hz and VSync to 61.783314 Hz.

- 0.127: Added 'I P M Invader (Incomplete Dump)' (Irem ????) [unknown dumper, Couriersud]. This is from an incomplete dump without documentation. The filename contained m10 and with a hack to work around the missing rom you get some action. The files are all different from ipminvad. Either this has been a prototype or eventually the famous "capsule invader".

- 0.123u1: Changed description to 'I P M Invader'.

- 0.122u4: Couriersud added samples to IPM Invader (just rename your old invaders samples to ipminvad to test). Added amongst others "capsule" dipswitch. Changed M6502 CPU1 clock speed to 1250000 Hz and VSync to 60.012483 Hz. Added dipswitches 'Capsules', 'Bonus Life', 'Coin A' and 3x 'Unused'.

- 0.62: Nicola Salmoria added 'IPM Invader' (Irem 1979?).

- 24th August 2002: Nicola Salmoria added IPM Invader to the Sky Chuter driver and fixed the colors in it.

- 0.37b6: Added (Testdriver) (irem m10 hardware).

- 12th August 1998: Malcor dumped I P M Invader (Coffee Break Invaders) by IPM.

- TRIVIA -

Released in January 1979. Known as the poor mans version of "Space Invaders".

Irem was founded in 1974 as 'IPM Corp.' in Hakusan, Japan. Like most of their contemporaries, the company's initial purpose was to produce and rent out electronic leisure machinery to various sections of the entertainment industry. With the advent of arcade videogaming and the hugely popular "Space Invaders" (1978), Irem opted to move into the development and manufacturing of their own titles. They rapidly released their own 'invader clone', the aptly named IPM Invader.

IPM Invader was a crude and shameless copycat of Taito's milestone, but yet the sheer popularity of arcade rooms at the time saw the game do well enough to convince the company that games were a viable business opportunity.
In 1979 they changed their corporate name to Irem Corp., an acronym for 'International Rental Electronics Machines'. This would stand until the mid-80s, when it would then be changed to 'Innovations in Recreational Electronic Media'.
For their first few years, Irem's output was average at best. If anything it could almost be considered poor: random invader clones and poorly produced action games disappeared amongst the numerous other titles of the day.

- UPDATES -

It is like "Space Invaders", with identical graphics. It uses a color monitor instead of a black and white monitor with a color overlay.

It has the addition of the famous 'coffee break'. What's the 'coffee break'? The 'coffee break' is a unique feature in IPM Invaders whereas after every 3rd wave or pattern of invaders, the 'coffee break' appears.

Another unique feature in IPM Invader is the 'capsules'. When dip switch settings are changed to advanced settings, the game becomes more difficult with the introduction of the UFO (mystery score ship) dropping 'capsules' that hatch into new invaders. The 'capsules' cannot be destroyed until they hatch, and are dropped across the screen to defeat the players 'narrow column' strategy.
