Trophy Bass 4 1.0.0.4 - You need at least 50MB of free space.. can create a patch ?

[DjDiabolik]

Actually i have the value managed by os and i can see the actually it's setted to a value between 16MB and 1408MB.

In various parts i see this value it's best to setted at:
Value RAM * 1.5 = Result

Instead i have 4GB (4096MB i thinks if correct) or Ram i need to set this value to 6144 MB ?? It's not a higher value ?

*EDIT*
Otherwise setted the value of Virtual RAM to 6144MB...... i have restart my Windows 10 and now on Tbass.ini:
[Hardware]
OpenGL=0
PhysicalMemory=2147483647
VirtualMemory=-1
ProcessorSpeed=1
VideoAccel=1

Virtual Memory it's setted to -1.......................... i thinks i need to fix the .exe or create a little patch if it's possibly......
