Karoshi Corporation will always be remembered for their outstanding MSX1 games that have competed in the MSXdev challenges. Pitpan as individual has also been instrumental in creating and organizing the original successful MSXdev challenges, along with the creation of assembler asMSX. For a number of years, both Pitpan and Jon Cortázar (Viejo_Archivero) haven't been involved with MSXdev anymore. Jon was making his name as RELEVO Videogames. On March the 3rd 2012, it was announced that the Karoshi MSX Community has taken over the organisation of the MSXdev contest, with both Pitpan and Viejo_Archivero at the steering wheel.
