Hi Calamity,
I post here because I haven't seen my problem elsewhere :
I would have liked to try your drivers on a configuration based on ArcadeVGA2 HD2400 (WinXP32).
After having properly uninstalled the Ultimarc driver, I installed your driver "crt_emudriver_9.3_1.2a_xp32_multisync".
Then, the executing of Arcade_OSD indicate "crt_emudriver not found".
Indeed, by checking the properties of the GPU, I notice the card didn't start because there is a code 10 error.
Are you informed about incompatibility between your drivers and those HD2400 from Ultimarc?
Does there exist a particular procedure with these GPU?
If that can be useful to you, here is a screenshot of this HD2400 device ID:
Thanks in advance for your assistance.
Bye
