Thanks shanki
The backforcefeeder program enables me to use both M2PAC mode and Compatability mode, therefore I do not need to reflash my arduino when changin the game, is this correct?
Correct! Once your arduino is flashed with the software included in BackForceFeeder archive, you don't need to touch it anymore, whatever the mode (RAW/M2PAC or Compatibility) you use. If I provide the Mega2560 for your Mega Adapter, it's already flashed.
I also don't need to have a PWM2M2 oder your adapter in order to use compatibility mode as it is handled within VJOY?
- If your original FFB boards are working, you don't need a PWM2M2. However, when using Sega Model 2 hardware, you need Sega Rally's Driveboard EPROM on your driveboard (it's the only Model 2 EPROM that BackForceFeeder supports for "Compatibility" Mode) to have FFB on all games. So, for example, a Daytona1 cabinet owner will need to burn Sega Rally EPROM or take a MultiFFB board. In your situation, as you own a Sega Rally cabinet, you already have Sega Rally EPROM on your driveboard, so you can already use Compatibility mode and have FFB on all games.
- If an original FFB board fails or is missing in your Model2 cab, you can order a PWM2M2 and your Mega Adapter will be able to communicate with it.
How do you switch between the modes then? Is there some command that needs to be sent to the arduino?
You switch modes in BackForceFeeder interface. There's an "App&Hardware" window where you select the "Target Hardware". There, you choose between:
- "RAW/M2PAC" mode to use original FFB (all the hardware has to match the game you play. In your case, it will be for Sega Rally 1 only, or SegaRally1+Daytona1+Virtua Racing if you swap driveboard EPROMs or use a MultiFFB board)
- "Comp_M2_SR1" mode to use emulated FFB on all games
- "PWM_Centered" if you use a PWM2M2 (emulated FFB on all games)
If I get the video converter it means I can just set my graphics card to 640x480 and the board will handle the conversion to 25khz?
The VideoAmp is not a converter, it's an EDID emulator. It means that when you use it, your PC sees a monitor with 25khz resolution and will send the correct signal. Nothing is converted. You will select something between 512x384, 1024x384 for progressive 25k res or 1024x768 for interlaced 25k res in your video parameters. 640x480 will not be available if your VideoAmp is set for 25k only.
Also what exactly is the MultiFFB? If I understand correctly it's a custom eeprom for the drive board that enables other game boards to be connected? Would that mean that if I get that eeprom I can play more games in M2PAC mode instead of compatability mode?
It's just a 8 slot driveboard EPROM selector. It's like swapping original Driveboard EPROMs, but with switches. It's a small board that goes where the original EPROM sits.
For Model 1&2, it allows M2PAC (= original FFB) for Sega Rally 1, Daytona 1 and Virtua Racing games on any of these 3 cabs (as they share the same type of driveboard, only its EPROM differs)
If I keep my stock M2PAC does it mean that I can only play only the games that use the same drive board as my Sega Rally?
I don't see any point into keeping your current M2PAC setup if you use a Mega Adapter with BackForceFeeder, as its functionalities are included.
And if you use only your M2PAC setup, you can only play the 3 games above with FFB (if you change Driveboard EPROMs)
And then last of all how much does the Model3 Adapter with the different options cost.. also could you tell me the price of the MultiFFB seperately as it might be useful for my Model2 cab and my stock M2PAC solution.
Shipping would be to Switzerland.
We'll see that in PM
