It seems that the program is not updated anymore and when i want to install in my nokia e51, the SDL-1.2.13-s60-2.3.4_armv5 file gives expired certificate. If i revert the phone year to 2006 or other years, doesen't work. SDL-1.2.13-s60-2.3.4_armv5 is from DOSBox_s60_bianry_dependencies archive. The dosbox_073_s60_20091207_rc2 archive i didn't tried yet, as i want it to install dependencies first. A dosbox lite exists ?
