SLotman has just released a new version of MSXPad, a Pascal IDE targeted at developing MSX software. In this version, many bugs were fixed and (preliminary) tooltips for functions and procedures were added. To top it off, an interesting and thorough tutorial on how to setup the program and how to do some basic stuff like converting and loading graphics, using copy's, playing sounds, and more has been released as well. At MSX Files, you can find MSXPad and its tutorial in the Utils section.
