0.138u2 [Luca Elia, XingXing]
0.104 [Luca Elia]

WIP:
- 0.142: Brian Troha corrected dipswitch names and added DIP Locations to Alien Challenge. Changed 'Unknown' to 'Unused' dipswitches.
- 0.139u1: Return to type safety. Changed address maps back into functions that build up the definition, rather than the whole tokenizing system, which lost type checking. Added a new module addrmap.c which implements the address map classes, and changed the macros to call methods on the address_map and address_map_entry classes which are strongly typed. Fixed a few incorrectly specified memory map entries along the way in LordOfGun driver [Aaron Giles].
- 0.138u4: Added missing YMF278B sound rom (yrw801-m).
- 0.138u2: Luca Elia and XingXing added Alien Challenge (World) (IGS 1994). IGS Lord Of Gun driver update [Luca Elia]: Implemented RAM based priorities. Added multi-sprite and fixed sprite list end. Corrected tilemap 2 size (wrong backgrounds in the final stage). Fixed crosshair position. Changed description 'Huang Fei Hong (Alien Challenge?)' to clone 'Alien Challenge (China)'. Renamed (hfh) to (alienchac).
- 23rd May 2010: Luca Elia - With the priority changes in lordgun.c, and the graphics roms dumped, Alien Challenge is now playable, also thanks to the protection patches sent by XingXing. This was the first combat game by IGS. Screen shots are from the World version, even though most text is in Chinese anyway. The Chinese version (currently in MAME as Huang Fei Hong) is partly dumped. It shares the sound program and samples roms, has an earlier revision of the program roms and lacks a dump of the graphics. By overlaying the upper part of the World version program roms, and by providing its own protection patches, it boots. The only difference I can see, using the graphics ROMs from the World version, is the program revision in test mode and the boot screen (it even shows the FBI logo). At any rate, I'll mark those program roms as bad dump (half size). The game uses a multi-sprite mode that was previously unimplemented, and also shows that the sprite-list-end handling in the driver was wrong. The missing background music still needs fixing. Thanks to XingXing, alexgizh, Smitdogg and The Dumping Union.
- 1st May 2010: Smitdogg - XingXing dumped Alien Challenge (World).
- 0.135u1: Changed description to 'Huang Fei Hong (Alien Challenge?)'.
- 0.131u1: Removed 2nd button.
- 0.104: Luca Elia added Huang Fei Hong (IGS 199?).
- 22nd January 2006: Luca Elia - Elsemi, master of the later IGS games, among many other things, points out there is at least another game running on the Lord of Gun (IGS 1994) hardware, Huang Fei Hong, of which a partial dump exists (without graphics roms). So I may look at that one next.
