some of you may have seen the topics on xentax and gamemodels.ru - blackracer and whitecarisma managed to import efo files in noesis of initial d stage zero
i noticed that a few tracks and cars have been removed in this version - so i checked stage 4-8 - also the characters have been removed from stage zero
looking at the efo files from stage zero in hex they start with "YABX" - the efo files from 6-8 are compressed? "YS" header
after checking them with the comtypescan / hexdump script the only algorithm is ZYXEL_LZS which converts the first few bytes to YABX
using this algorithm in a bms script it will print out this error: "LZS_Unpack: invalid dict: 062E1FB1 < 062E2000 (tag=0, offset=0x55)
there is a version of initiald 5 - which has a internal tool called xafmaker.exe with some dll files - this tool can extract the xaf of ID4 and 5 ...
you can also create xaf files - but this will need a xac (config) file - initial d stage zero does have those xac files - but did not packed the game
looking at the xac files - it used COMPRESS_LZW - the problem is, version 6 to 8 are using different dll files - thats why the archives cant be unpacked with this tool
fun fact: i tried the following combination: the xafmaker (ID5) with the car.xac (StageZero) - this packs the AE85L_bonnet.efo (YABX /uncompressed) to (YS /compressed) compared the newly created xaf containing this one YS with the compressed AE85L_bonnet.efo (YS) of ID8 - they match 100%
so this means the YS files are using a LZW compression?
