I tried getting the latest SoftGPU version running in VirtualBox 7.2.4 on ZEN 4 (Ryzen 9 7950X) and the documentation needs a few updates so people don't trap in the same issues i have.

1. AMD Zen 2+ Optimizations is required for any modern Ryzen Zen 2+ CPU, otherwise windows 98 crashes randomly a lot with virtual memory related bluescreens.

2: AC97 is only working when 1. is applied before the windows setup and only accepts Intel ICH AC'97 drivers. Realtek ones are not compatible!

1. Do not install any drivers or enable DMA before 1. is applied!

Can you @JHRobotics adjust the documentations for virtualbox? That would be great and removes a lot of questions and future problems.

Also it would be wise to add a few lines for making the use of virtualbox less annoying:

• CD ISO, FTP file transfer and mounting the drive directly is the only way to get games to the guest VM, USB 1.1 is too slow. RebexTinyFtpServer is a simple solution on win hosts that supports older FTP protocols. Filezilla 2.1.9a runs great in win98. Required bridged network of course and a full DHCP network setup on the outside. The alternative is mounting the VHD drive directly and copy the files directly into that.

• No aspect ratio scaling in neither window or fullscreen VM output, so you always have to use your native screen resolution and need to enable (1440p or 4K) in SoftGPU

• Use screen resolutions in height that matches your native resolution, otherwise you may get a tiny screen in the center
