LÖVE

You need to put the PNG in the .love file before combining it with the .exe.

Forgive me for not understanding. I put the png into the .zip file, then I change the .zip to .love.
After these steps I make my exe.

Is this not the correct operation?

.love files are case-sensitive and this really sounds like a case problem.

I thought so, but couldn't prove so.
I'm using all lowercase for everything including the file extension.

You could upload the .love here, we can probably tell what's wrong then.

The code is extremely short, so I'll just paste it here.

function love.draw()
love.graphics.draw(g_Effect, 200, 100)
end
g_EffectImage = love.graphics.newImage("test.png")
g_Effect = love.graphics.newParticleSystem(g_EffectImage, 30)
g_Effect:setLifetime( -1 )
g_Effect:setDirection( math.pi )
g_Effect:setSpeed( 40, 40 )
g_Effect:setColor(255, 255, 255, 222, 255, 255, 255, 0)
g_Effect:setParticleLife(.5, 2)
g_Effect.setEmissionRate(g_Effect, 5)
g_Effect:setRadialAcceleration( 0, 0)
function love.update(deltaSeconds)
g_Effect:update(deltaSeconds)
end

runs perfectly as a .love
bluescreens as an exe "could not open file test.png. does not exist"

That doesn't really help us, since we can't see whether the .love file was wrongly packaged or anything of that kind.

It certainly looks as a uppercase/lowercase problem.

Sorry if I sound like repeating what others have said, but you have checked the file *in the hard drive* is called exactly test.png, all lowercases - no test.PNG or Test.png.
If it is, it will work as an uncompressed windows folder but not as a zip file.

If this doesn't work, please upload the .love file.

uploading the .love file.
I assure you everything is lower case.

apparently PNG gets force-uppercased when I package in my zip, then I cannot change file extensions in the zip...
Is there a way to zip the file without my windows hacking my things?

this issue has been resolved. stupid windows file extensions.

Thank you for your helps!!!
