Similar titles being released on both platforms does not indicate similarity in the hardware or it's emulation as alot of time and money goes into porting games to multiple home console platforms.

As for the Saturn, it's kind of a beast to emulate. The original hardware had a pair of identical Hitachi SH-2 32-bit RISC clocked to 28.6 MHz.

On top of that it had a SH-1 32-bit RISC processor controlling the CD-ROM. This was going to be the only processor until the original PlayStation's CPU specs were announced.

Other chips on the Saturn included:
# Custom VDP 1 32-bit video display processor (running at 7.1590 MHz on NTSC Systems, 6.7116 MHz for PAL Systems)

# Custom VDP 2 32-bit video display processor (running at 7.1590 MHz on NTSC Systems, 6.7116 MHz for PAL Systems)

# Custom System Control Unit (SCU) with DSP for geometry processing and DMA controller (running at 14.3 MHz)

# Motorola 68EC000 sound controller (running at 11.3 MHz / 1.5 MIPS)

# Yamaha FH1 DSP sound processor, "Saturn Custom Sound Processor" (SCSP), running at 22.6 MHz

# Hitachi 4-bit MCU, "System Manager & Peripheral Control" (SMPC)

Every single one of these would need to be emulated in software in order to get Saturn games running properly.

Not a task I'd wish on my worst enemy....
