Is the 3D-models ripping from Model 2 games possible?
#368843 - 08/18/17 03:34 PM


I would like to take a models from Gunblade NY and Virtual Cop 1/2 concretely. And I would like to know about possibility of ripping from Model 3 (Step 2.1), Namco System Super 23 (GMEN) and Konami Viper games also.

You'll need to reverse-engineer the model format for each game then. Good luck

About the Gunblade NY - I read in the Model 2 MAME driver, this game stores its models in


Code:

mpr-18980.17
mpr-18981.21
mpr-18982.18
mpr-18983.22



files. Now main piece of question is how to take this models from there. Besides this, the textures are stored separately from the models also, in the mpr-18985.27 and mpr-18984.25.

I've tried to extract some models from model1/2 before. Main technical difficulties are:

1. Most models are stored as many small parts. The way how those parts are orgnized requires lots of time to reverse-engineering. More over, the ways of orgnization may be different from game to game, even with the same kind of hardware;

2. Color and texture data are stored seperately, and pointers linking color/material/texture/polygon data are also scattered here and there, sometimes mixed with program code;

3. Most of those 1990's 3D hardware used z-sort, instead of z-buffer. When extracted them to a modern 3D rendering engine, one may experience some unconfortable visual effect. There were also many 'tricks' when using z-sort, the head-light on the subway train in vcop2, for example.

BTW, can anyone remember, if this bus really appears in vcop2, model-2 arcade version?
Thanks!
