Atlus is bringing their PsOne classics to PlayStation Network starting with the original Shin Megami Tensei. The PsOne version is an enhanced port of the Super Famicom game with an easy mode and some graphical touchups.
Shin Megami Tensei costs a bit more than other Game Archives releases at 1,000 yen ($12). It’ll work on a PSP and/or PlayStation 3. Before you hit the download button, please note Shin Megami Tensei, like other Game Archive releases from Japan, is entirely in Japanese. If I remember correctly, Shin Megami Tensei has kanji too.
Now to wait and see if Atlus USA follows suit and distributes some of their PsOne library on PlayStation Network.
