Hello.

I'm not sure if this issue was already covered, I did search for it a few pages back but did not find mention to it so I'm sorry if this is a dupe:
- Sega Rally 2 will not show game mode nor car models in the selection screen if coin is inserted before attract mode is shown.
- Still judging from Sega Rally 2, I was (am?) about to mention that there were glitches introduced in the last few versions (after old r757), but it seems that increasing the PowerPC frequency solves those graphical issues entirely.

Great work, congrats.

Since Jiterdomer's last build, I have made even more fixes to the SCSP emulation, including:

1. Good-sounding FM. I had to activate the STWINH slot in the code (one of the SCSP's 32 programmable slots). It was originally set to 0, which made FM-based synths in VF3 sound awfully quiet (namely the stage themes of Akira, Taka-Arashi, and Pai), and with the FM_DELAY code from MAME, the samples often distorted if this was disabled.

2. Ported MAME's DSP code over and kept ElSemi's old DSP logic in SCSP_w16 in favor of a new config option called LegacySound. While the MAME core makes most sound effects processed by the SCSP's DSP sound much better, this unfortunately introduced a bug in Fighting Vipers 2 on Bahn's stage where the music hangs and turns into EARRAPE! On the flipside of things, Sega Rally 2's engine noise seems to be working now, as well. The Cave stage music in VF3/VF3TB does not fade out anymore, either, and there is no more excessive reverb with the new core.

I will share the current state of the code and a build in another thread soon, but I'm happy with the way the progress is going as far as audio.

Good job! Here's the SCSP build for others who want to build your own:

Hi Developer's
Changed to SDL2 and can't run on PC with Ivy bridge CPU
Runs on sky Lake CPU PC
Is SDL2 not compatible with older CPUs?

google translation

[Ian]

what error do you get?
maybe sdl2 needs new dll file?

[model123]

Ivy Bridge PC and Sky Lake PC use the same SDL.dll, SDL2.dll and supermodel.exe
When you enter the command

Supermodel: A Sega Model 3 Arcade Emulator (Version 0.3a-WIP)
Copyright 2011-2019 by Bart Trzynadlowski, Nik Henson, Ian Curtis,
Harry Tuttle, and Spindizzi

Is displayed, but does not run. Return to command input
The error.log only says

Supermodel v0.3a-WIP Error Log
------------------------------
Started as:
argv [0] = supermodel
argv [1] = roms / vf3tb.zip

hi,
already trying to answer many days ago, but the forum seems to have restore its database from a previous date
anyway
may I ask you if you use a build from other generic emulation web site ?
Just to be sure, I tested their realease, and same for me : just crash without error. I have a really 12 year old computer under win7
in other hands, building the project by myself, there is no trouble
