Ok, i want really bad to play this game with my vita. Why? For Maria of course. Not the mod Maria with frurry powers of psp version. Then I remember of being sucess to emulate Castlevânia X under ten years ago with a low pc with a emulator. I remember doing this with dos, but maybe I only dont remember right. Researching i found SSE, a saturn emulador for dos. The oficial page says it runs castlevânia ok and my hope start here. What I did so far. Download SSE 070 DOS and put it in a /emulator/sse directory. Download Dosbox 0.74 and install Configurated cfg of dosbox to mount sse dir. Put japanese bios inside bios directory and updated the sse cfg. Put my backup DRACULA_X.bin and cue inside roms directory download CWSDPMI.exe and CWSPARAM.exe. The emulator needs the first to work, but also try to acess a swapfile with i dont have at c:\cwsdpmi.swp. CWSPARAM i use to disable the swap file but i dont know what values put in the other options. Maybe this is the error. Anyway, the program return a error exit sigsegv. But there´s also a catch. The emulator need a header file of the game. The 16 first sectors extrated to a file inside headers directory. A program comes with the emulator to do it, but need a lib from old cd drive systems to work, no sucess under win 8.1. Also the documentation say about use CDRWIN as a alternative, but i dont know how to. what i did was use a hexadecimal program called HxD and deleted all sectors beyond 15. Can anyone give it a try? If it run with doxbox we can try the retroark versiion.
