Another game that I remember distinctly & fondly from my youth: Alcon!  It was in the very back left corner of my local Putt-Putt mini golf.  It ate many a token of mine.  I thought the ability to choose ship upgrades really added a lot of depth to the basic vertical SHMUP concept.

I was reminded of it when DrFrag picked Terra Cresta.  I hope you all don't find Alcon to be too similar to Terra Cresta--I figured I might not have another chance to pick one of my sentimental favorites in the future, so I best do it now!   ;D


As Alcon isn't emulated in MAME, we'll play the bootleg version: Slap Fight.


Competition Rules:

- You can only use the slapfgtr.zip ROM, with default MAME settings which are: 

Lives: 3
Bonus Life: 30000 100000
Difficulty: Medium
no MAME cheats! (exploiting any in-game tricks programmed into the game itself is just fine)

- Last day is Wednesday, July 15th (11:59:59pm Pacific Daylight Time), 2009.
 
- High score wins (if tied, winner will be chosen by which player progressed further in the game).

- No savestates, savestate practices, etc during the round.

- MAME INP recordings are optional, but encouraged!

- A screenshot is required to enter a score (press F12 to save screenshot showing your final score) or take a photo of the screen if playing on a real machine.

- If you're a MARP competitor on this title, keep in mind this is just a friendly competition amongst forum members, so maybe you shouldn't enter. However, if you're a forum member and this is a game you're good at and nobody knows about it, this is your time to shine!


I will offer a prize again.  Some sort of minor video game memorabilia: perhaps an Intellivision cartridge signed by its author, a few TRON trading cards, or some other small token gift...


Have at it!!!  My quickie preliminary stab at the game just now produced 81,560.  I know I can do much better, and I'm sure many of you can too!

Note that (at least on my patched MAME .115), high score retention for slapfgtr is not supported, so remember to capture your score before quitting MAME on this game!!!

Thanks,
-Jason
Ginsu Victim:
I know I've played it on my A-Z journey through MAME (currently on M), but I don't remember it and I'm having trouble finding a screenshot at the moment.
CrazyKongFan:
What version did MAME start emulating this game? It shows as not working on .106 (the version used for submitting scores to Twin Galaxies...they actually use the bootleg English version of Slap Fight)

Version history below.  There are a few versions of Slap Fight, so I'm not 100% sure which bootleg is which, but it appears that only 1 minor change has been made since .104u9, so I'm not sure why it wouldn't be working in .106...

Thanks,
-Jason


info 0.33b2 [Keith Wilkins]

TODO:

Dump 68705 MCU. Only the bootlegs are working.
WIP:

0.123u1: Corrado Tomaselli corrected the clocks in Slap Fight. Changed Z80 CPU2 clock speed to 3MHz.
0.104u9: David Haywood added clone Slap Fight (set 2) - dump labeled Alcon, but GFX in tile roms clearly read Slap Fight.
0.104u8: David Haywood added clone Slap Fight (bootleg).
24th March 2006: f205v dumped Slap Fight (bootleg).
12th September 2005: Guru - Slap Fight with a 68705 MCU arrived. Thanks to Tingoes.
16th April 2005: Guru - Alcon (with 68705P5, unfortunatley it's protected!) arrived. Thanks to the good boys at the Italian MAME Forum.
14th March 2005: Corrado Tomaselli dumped Slap Fight (set 2).
0.35RC1: Marco Cassili added clone Alcon. Not working due to protection.
0.34b4: Sebastien Chevalier improved music tempo in Slap Fight.
0.34b1: Christoff Feldtmann improved gfx in Slap Fight.
0.33b7: Keith Wilkins accurated colors in Slap Fight. Renamed (slapboot) to (slapbtjp) and (slpboota) to (slapbtuk).
0.33b2: Keith Wilkins added Slap Fight (Taito 1986) (preliminary) and clones (Japanese Bootleg) and (English Bootleg). Due to protection, the original version doesn't work. Scrolling is jerky. Music tempo is too slow. Use one of the bootlegs instead. The three games are identical, only the 1st CPU EPROM is different which shows up in the boot message, one if Japanese domestic and the other is English. The proms which MAY be the original slapfight ones currently give a hardware error and fail to boot. 
CrazyKongFan:
OK, reading your original post closer, it does appear you are using one of the bootlegs, as the original has an unemulated MCU (as does Alcon). I'd just assumed the parent set was being used, but the parent set doesn't work.
