The emulator needs a kickstart system ROM file. Please drag the missing file into the empty chip socket. Or just touch or click the sockets.
Once loaded vAmigaWeb will try to store these files to your browsers local storage. Then on subsequent starts it will take the rom files from your browsers local storage instead of asking you again for them.
... after created you can change the position of the action button by dragging ... when clicking the action button with a long press it
goes into edit mode which takes you right back to here ...
Warning: no rom-chip in floppy drive installed. D64 and G64 files are floppy images ... loading of files with these extensions will require a floppy rom. Head over to roms setting and provide the rom first. Or try to load a file with a different extension.
