How to Test optimized GDI games for DS in Windows 10?

[Ro Magnus Larsson]

Is it possible to test GDI-Opt games for Dreamshell in my PC?
In order to not force the Dreamcast console re-booting and re-booting many times to test games compatibilities then save them in the DS HDD

Thanx

You can test on emulator, just put GDI to build directory and create CDI with DS.

Ok, they are many steps there, I mean, to test the games with DS in the Windows PC in order to try presets too. I guess there is NOT a DC emulator which boot optimized GDI ?

Test DS presets on Windows?! The thing is that some DS presets differ from Dreamcast revisions even when tested on real hardware. For example, some presets from a PAL console may not work on an NTSC console. Moreover, there is no guarantee that a preset that works in Windows will work well on PAL or NTSC.

On emulator you can test only memory areas, other stuff better test on real hardware.
In the case of an emulator, the data is loaded from the same "optical drive", so compatibility there will be better in some games, because no fragmentation, sector size is the same and IRQ is the same as the game expects.
