Gens is developed by St�phane Dallongeville and has been coded 35% in C/C++ and 65% in Assembler. It runs under Windows 95/98/ME/2000/XP and requires DirectX 7.0 or above to be installed on your system. The genesis compatibility of Gens is very high : * about 93% of games work perfectly or with no noticeable problems. * a further 5~6% of games are playable with minor problems. * 1~2% of games are unplayable. (figures quoted are for Genesis/Mega-Drive only from tests conducted by the Genesis Project and are approximate.) The compatibility for Sega-CD/Mega-CD emulation has been estimated as being about 90% or higher and the 32X system compatibility turn around 75%. _______________ /##############/ /# DISCLAIMER #/ /##############/ ��������������� GENS � 1999/2000/2001/2002 St�phane Dallongeville.

For Genesis/Mega-Drive emulation you will need: Minimum System: Recommended System: * Pentium 200Mhz+ * Pentium II 300 Mhz or above * 32Mb of Ram * 32Mb of Ram or more * 2Mb Video Card with DirectDraw * A good video card like a TNT Support in 15/16bpp mode * Win9X/2000/ME/XP * Win9X/2000/ME/XP * DirectX 7.0 or above * DirectX 7.0 or above [+ Gens will run on a Pentium 133 or above, but a Pentium 200Mhz is needed to achieve a reasonable frame rate!] If you want to use the Sega-CD/Mega-CD emulation you will also need: Minimum System: Recommended System: * PII-233Mhz or K6-300Mhz * PII-333Mhz or K6-2-450Mhz * CDROM drive (Single Speed) * CDROM drive (Quad Speed) * The latest ASPI drivers * The latest ASPI drivers * Sega-CD/Mega-CD bios files * Sega-CD/Mega-CD bios files For 32X emulation you will also need: Minimum System: Recommended System: * 800 Mhz CPU * 1 Ghz CPU * 32X bios files * 32X bios files On my machine (Duron at 1Ghz) all 32X games runs at 60/50 FPs in fullscreen 320x240 and sound set to 44100 Hz. I guess you can play some 32X games on slower CPU (550-700 Mhz) but you will need to downclock manually the SH2 CPU clock (see section 32X). ______________________________ /#############################/ /# DEFAULT KEYBOARD SETTINGS #/ /#############################/ ������������������������������ The default keyboard layout for players 1 and 2 are shown below, you can of course change these to whatever keys you wish or map them onto a Windows compatible Joystick/Joypad.
