Question "Illegal Instruction" Error - Linux Gaming on Celeron 333MHz

[kieferz7777]

I have been trying to run Undertale on increasingly old hardware. I had success on a Dell Inspiron 8600 using Puppy Linux.
I am now trying to run the same exact OS and command on laptops with intel celeron ~300MHz processors. but when I run ./runner or sh run.sh it gives the error "Illegal Instruction"
Is there a different OS or a package I can install to fix this?


Still a little new to the forum. I dont know if it belongs in another section or not, but my best guess was an incompatible CPU

I have tried two different laptops with the same error:
IBM ThinkPad 240
Sony Vaio PCG-N505VE
Operating System: Precise Puppy 5.7.1

You might not have enough ram. Also, those cpus are old enough that they literally may not have the instructions set in the cpu, hence the error.

Both good points. At one point I thought it was the CPU, because I was able to get it to work with 256MB ram before, and then on a different PC with two 128MB modules it didnt run. I think it might be best to use a VM to figure this out. I did have a few errors in VM when I moved to other rooms on 256MB ram that killed the game, but that wasnt illegal instruction

It's always hard say what it could be since you're literally pushing the architecture into use cases the original designers never intended.
