You can fool such emulators by attaching an 8KB dummy file to the end of original ROM before patching. Otherwise it will not run the ROM correctly. The problem is: Most emulators require the game to have an exact size (multiple of the page size of the megarom in question) to execute a ROM.

You can apply the patch just as you do with an IPS patcher. Goto ExecROM SourceForge page and download XPCtools. To run the game just type ExecROM GRADIUS2 at the MSX-DOS prompt.Ģ) Apply the patch to the ROM.

It will not only implement the DynamicVsync (for MSX1 & MSX2), many speed optimizations and some tricks: it also includes a much-desired feature: SmoothScroll for MSX2+ and MSX Turbo-R! This new patch is not just the same as previous ones. As a result, the game drops frames constantly, running noticeably slower than its predecessor: Gradius (a.k.a. Also, the game is far too CPU-intensive for a standard 3.57MHz Z80A to sustain a full frame rate. As with many other Konami megarom titles for MSX, it suffered from the bug in the timing routine that lets it run at twice its normal speed if the processor is fast enough. Nemesis 2) is a spin-off story of the Gradius series, developed specifically for the MSX and later ported to X68000 and PSP under the title 'Nemesis 90 Kai'.
