Hello, and welcome! 🙂
Win95 is terrible to set up, there can be numerous reasons. If it hangs on the boot screen, you might want to check your settings again. If there’s only the slightest bit off with the -size parameter, it won’t launch. Also, make sure you do not use SVN core, it’s a bit buggy in Win95.
In my case (512 MB image), it’s like this (“0000-0000” is my external sd):
imgmount c /storage/0000-0000/Games/PC/Win95/c.img -t hdd -fs fat -size 512,63,32,520
