"JUST FOR FUN",yet another arcade emulator. RELEASE 0.20 ^ ^ ^ Just for Fun is an emulator which runs some arcade games; all of the emulations are playable, even if no one of them could claim to be arcade perfect. USAGE To operate JFF just unpack the supported romsets in the corresponding directories (that is,"AMBUSH","HIGEMARU",etc.). Run the emulator by command line by typing: JFF [game] [-s] "-s" option is for disabling sound emulation; "game" must be any of the following: AIRBUST Air Buster (aka Aero Blasters) AMBUSH Ambush GETSTAR Getstar HIGEMARU Higemaru MNIGHT Mutant Night NINJAKD2 Ninja Kid II NINJAK2A Ninja Kid II (alternate romset) PSYCHIC5 Psychic 5 VASTAR Vastar XXMISS XX Mission This emulator is for plain DOS, but it will probably run under W9X; it has no joystick support, but prelimary sound code for some games is available. The soundblaster detection relies on a properly configured blaster environment variable: you should have a proper statement in your autoexec for it. Since the sound driver is really experimental, I don't know whether it'll work on any machine other than mine. !!! IMPORTANT !!! this emulator ISN'T TO BE DISTRIBUTED WITH ROMS...so don't ask me for! KEYS AND MAIN FEATURES: If the emulator doesn't run full speed disabling vertical sync by pressing the TAB key should help; if the speed is still unreasonable you can resort to go frameskipping. Control keys: ARROWS,ALT,CTRL player's control 1-2 1/2 player start 3-4 insert coin ENTER switches ALT and CTRL assignment TAB toggles vertycal sync on/off F1-F2-F3-F4 frameskip 0-3 F5 cpu reset key ESC quits emulation SUPPORTED GAMES INFO: ### AIR BUSTER ### ROM directory name: AIRBUST Rom names: PR-11J BIN 131,072 PR-14J BIN 131,072 PR-21 BIN 131,072 PR-001 BIN 524,288 PR-02 BIN 65,536 PR-000 BIN 524,288 PR-200 BIN 262,144 Features: No sound emulation.

Colors are completely made up, because color proms weren't available when I wrote my driver. ### GETSTAR ### Rom directory name: GETSTAR Rom names: GS_05 ROM 8,192 GS_02 ROM 32,768 GS_03 ROM 32,768 GS_04 ROM 32,768 GS_01 ROM 32,768 GS_06 ROM 32,768 GS_07 ROM 8,192 GS_08 ROM 8,192 GS_09 ROM 32,768 GS_10 ROM 32,768 GS_11 ROM 32,768 GS_12 ROM 32,768 GS_13 ROM 16,384 GS_14 ROM 16,384 Features: Colors are hand made, I need color proms to fix them! ### HIGEMARU ### ROM directory name: HIGEMARU Rom names: HG1 8,192 HG2 8,192 HG3 8,192 HG4 8,192 HG5 8,192 HG6 8,192 HG7 8,192 HGB1 256 HGB3 32 HGB5 256 Features: I emulated this game because I was really curious to play one of the first games ever made by Capcom. Higemaru emulation has got sound support. ### MUTANT NIGHT ### ROM directory name: MNIGHT Rom names: MN13-B23 BIN 65,536 MN11-B20 BIN 65,536 MN12-B22 BIN 65,536 MN10-B10 BIN 32,768 MN1-J7 BIN 65,536 MN2-J12 BIN 32,768 MN3-J14 BIN 32,768 MN4-J16 BIN 32,768 MN5-J17 BIN 32,768 MN6-J19 BIN 32,768 MN7-E11 BIN 65,536 MN8-E12 BIN 65,536 MN9-E14 BIN 65,536 Features: No sound emulation. If the rom check fails (this will happen if the bad dump is used) press fire button to skip it. ### NINJAKID II ### ROM directory name: NINJAKD2 Rom names: NK2_08 ROM 65,536 NK2_12 ROM 32,768 NK2_11 ROM 65,536 NK2_10 ROM 65,536 NK2_09 ROM 65,536 NK2_07 ROM 65,536 NK2_06 ROM 65,536 NK2_05 ROM 32,768 NK2_04 ROM 32,768 NK2_03 ROM 32,768 NK2_02 ROM 32,768 NK2_01 ROM 32,768 ROM directory name: NINJAK2A Rom names: NK2_08 BIN 65,536 NK2_12 BIN 32,768 NK2_11 BIN 65,536 NK2_10 BIN 65,536 NK2_09 BIN 65,536 NK2_07 BIN 65,536 NK2_06 BIN 65,536 NK2_05 BIN 32,768 NK2_04 BIN 32,768 NK2_03 BIN 32,768 NK2_02 BIN 32,768 NK2_01 BIN 32,768 Features: No sound emulation. Due to experimental color mapping code the emulation is still slow, even if a P133 is more than enough. ### PSYCHIC 5 ### ROM directory name: PSYCHIC5 ROM names: P5A 65,536 P5B 65,536 P5C 65,536 P5D 32,768 P5E 65,536 P5F 32,768 P5G 65,536 P5H 65,536 Features: No sound,of course... Demo still doesn't play right; window scrolling is not emulated (but you will notice that only if you finish the game). By the way...color effects emulation (SW button,grey screen etc.) is completely arbitrary (and very slow); information on what PRECISELY should happen would be appreciated. ### VASTAR ### ROM directory name: VASTAR ROM names: C_C9 ROM 8,192 C_F7 ROM 8,192 C_F9 ROM 8,192 C_N4 ROM 8,192 C_S4 ROM 8,192 E_F2 ROM 4,096 E_F4 ROM 4,096 E_H4 ROM 4,096 E_J2 ROM 4,096 E_J4 ROM 4,096 E_K4 ROM 4,096 E_L4 ROM 4,096 E_N4 ROM 4,096 E_N5 ROM 4,096 E_N7 ROM 4,096 TBP24S10 6M 256 TBP24S10 6P 256 TBP24S10 6S 256 Features: No sound emulation. ### XX MISSION ### ROM directory name: XXMISS Rom names: XX11 4B 32,768 XX2 4B 16,384 XX10 4C 32,768 XX1 4L 32,768 XX3 6A 32,768 XX4 6B 32,768 XX5 6D 32,768 XX9 8E 32,768 XX8 8F 32,768 XX7 8H 32,768 XX6 8J 32,768 Features: Some funny CPU sync problems ("water shoots" on dry land). 50 Hz update instead of 60 Hz due to resorting to strange vid-mode.
