Great! Thanks. Selecting which game to play and redefining keys are possible,too. This is is perfect and better than I expected. Actually I didn't have to patch exe files. (Though it was good experience) Thanks again 😁

I examined this program carefully, and I found out that it utilizes interrupt vector table #82h . It loads IVT #82h(0000:0208~020B) into ES:BX, and then copies [ES:BX], [ES:BX+1], ..., [ES:BX+Fh] onto [DS:197h], [DS:198h], ..., [DS:1A6h] respectively. It assumes these addresses contain key scan …

It looks like redirection part is the weak point of current DOSBox.

Myself reply :happy: Use VC7.1(a.k.a .NET 2003) to compile with no problem. Or, you can use VC7.0(a.k.a .NET 2002) and overwrite VC Toolkit 2003 files into VC7.0 folder . Important Fact : VC .NET 2003 is free except IDE. Microsoft guys are freely distributing VC7.1 without IDE, i.e, VC Toolkit 2003 …

I got some information about DOS/V games. DOS/V games use PLAY5V.COM, which controls OPL3 chip(Sound Blaster 16) directly. OPL3 chip was not so generally used, so getting source codes and samples is not easy :( But you can analyze PLAY5V.COM if you are persevering. My Question : How well does DOSBox …

DOSBox emulates memory, so if you run Nanpa2 (and other Japanese games) on DOSBox you can run it. Even on Windows 98 and Windows 2000 you can run it. (I mean if you are lucky. It's related to environment variable, i.e, Autoexec.bat and Config.sys, so more chance to fail.) Note that Nanpa2 displays …
