No version of the PC Engine CD-ROM formats upgrade the PC Engine ram/memory/hardware. The Sega Saturn ram carts do the same thing, allowing the base hardware to use a larger segment to run content from, but does not upgrade system/work/video/misc "ram". The FDS also downloads mini roms to a small space and has the same kind of bottleneck, without upgrading the actual Famicom hardware, other than running additional sound in parallel. The batteries in cart games which save progress do not turbo charge the console hardware either.
The N64 ram expansion however, upgrades the actual hardware. The PCE CD system cards "upgrade memory" no more (but arguably less) than different sizes of cart roms are "upgrading memory".
If you refuse to research what you're commenting on to learn how these things work, then just stop commenting.
The Arcade Card saw few releases because PCE players were content with the SCD format and it launched during the 32-bit generation, while NEC was already showing off the PC-FX at the same time. Sapphire was released almost 2 years later and barely had any copies pressed because everyone was playing 32-bit consoles. Where I lived, 16-bit games sold for $60 - $70, but many SNES games sold for $100 - $150. I know, because I bought most of them, spending $1000 on a handful of games.Quote:
Sapphire was never released and the Arcade card cost a fortune at the time . But it game a massive rise in performance , compare any SNK Arcade card game to their Mega Drive or Snes version for proof
The Arcade Card does absolutely nothing to increase performance, it only supported games with enough content for the PC Engine to flex its muscle with, the same as giant sized carts. The larger Arcade Card games are comparable in size to Star Ocean, Tengai Makyou Zero and SFA2 for SNES/SFC. The extra rom size didn't give a rise in performance to the SNES, it only gave it more assets to take on. SFA2 doesn't run nearly as well the SFII ports, because taking on so much only strains the hardware and doesn't help it.
Neo Geo games with smaller roms than SNES/Genesis/TG-16 games still massively outperform them, because of the power of the Neo Geo hardware. Do you really believe than a 74 meg uncompressed Genesis port of Viewpoint would run the same as the Neo Geo version? Raiden for TG-16/PCE has a smaller rom than the arcade version, yet it tosses around twice as many sprites. Is this proof that smaller roms/"memory" equals more power? Or do we just need to exercise common sense?
