Toyota Celica for Atari ST Adapted for hard disk run, TT, Falcon . Used tools, SW : STX image analyser (by me), STX to ST converter (by me), HxD - hex and file editor (freeware) . Steem Debugger (main tool). Modded Steem Debugger for finding stackframe related problems. PaintShopPro for cover scan conversion to TGA, Photochrome for converting to PCS, own simple SW to depacking it to PCH. Devpac 3 assembler. Total Commander. Drive Imager for writing onto CF, SD cards and hard disks. Video Dub for capturing and processing video from oldies > YouTube . Some Html editors for WEB pages. Src: STX img. of org. Removed copy protections, manual protection, many checksums activating in later stages. Stackframe problems on 68030 fixed, etc. Exit to Desktop and gamestate save options. Extra files in archive (not belong to game self): HAGA - new development, cmpatible with all decent hard disk drivers, 1GB Falcon partitions and/or lot of RAM occupied at game launch. HAGA is function library, for now with 12 functions, what is enough even for gamestate saving. Use RUNME.TOS for starting game. - exits to Desktop. Before it may want to save gamestate: press / - it saves in aprox. 2 seconds and continues game. GSAU.TOS - autosave flag . Save format is TOS executable. Additional 500 bytes spent is worth of easy usage: just doubleclick savefile, and you are in 2 seconds back in game, at pos. where you saved state. Only 500 bytes ? Yes, because we use library calls. Little more about HAGA: Abbrev. from 'HArddisk Gaming Atari' . Goal is to support all common tasks needed by for hard disk run adapted old Atari ST games (made usually for work only from floppies). Additional funcions are exit to Desktop and gamestate saving/restoring, called snapshots too. Adding/viewing comments in snapshots. Autosave. One way of disk accessing by HAGA is RAM area swap, what results in high com- patibility (with all decent hard disk drivers). Speed problems are resolved by: Using PMMU instead SW swap on TT and Falcon. Direct writing to destination whenever it is possible - so code splits loadings by need. Smart MFP timer and interrupt handling by switch to TOS and back to game - no timer Data read (the slow part) at all, for instance . PP, Febr. 29 2012.
