Sensible World of Soccer has 2 executables on the first disk. One is designed for 512k chip and the other for 1MB chip
Enhancements must be in the sfx.
DamienD I think 1MB chip is rarely required
Operation Stealth is quoted in your example, but let's check Whdload version
http://whdload.de/games/OperationStealth.html
Yes, 512k chip and 700k fast. Actually adding fastmem allows to run it.
Most non-AGA games only require 512k chip. Some tend to fail with only 512k fast because of, say, second drive. And yes, old whdload slaves were lazy and didn't use expansion memory, and very old slaves couldn't use it either since whdload didn't support it, so 1Meg games were just 1Meg chip games. Trying to kill that legacy ATM.
