Kuniji Ikeda has found a way to get V9958 as well as Y8950 chips. However, to keep the chips affordable, he should order quite large amounts at a time.

The V9958 is the VDP of MSX2+ and MSX turboR computers. It is needed to convert an MSX2 to an MSX2+. The chip unleashes SCREEN 10 t/m 12 and diagonal scrolling mode. The Y8950 is the legendary MSX-Audio chip set as featured in e.g.

At last I finished the complete design of the System Architecture for the LPE-Z380 for MSX. The design includes mixed HW 50% and SW 50% for each particular interface. When the user wants to have MSX interfaces he loads the MSX patch to specific card. For Example: for Video card he load the V38 patch when he wants to have video V9938.
