Sure. Go right ahead !

Hehe.
I KNOW you don't care about efficiency (speed or .exe size) but that silly
PNG2BMP.exe converter is 90112 bytes and requires CWSDPMI.exe (20217 bytes)
just to get started. They are BOTH obviously external to Arachne, just like
any unzipper would be. And PNG2BMP is SLOW.
I know, you think 32 bit operation must be faster.
Hehe. It just lets programmers write slower code. <G>
In extreme contrast, the .ZBM unzipper is 2917 bytes (yes, 2917 with NO zero),
requires only 64k of 16bit DOS memory to run, requires NO additional software
other than DOS (like a 32 bit bootstrapper), and runs like greased lightning !!
Almost TWICE as fast as PNG2BMP on a 100MHz '586 using PNG examples from GWS
DOS version 0.7. Of course, it's written in ASM.
Thanks for helping me make that comparison. <GG>
