Games that allow extensive customization of the player's appearance, as in Animal Crossing and The Sims, typically rely on 3D texture mapping so that the changes to the appearance can be seen from all angles.Īn NES game with customizable characters, such as Cocoron, has to store each animation of each body part seen from each angle and composite them at runtime, either drawing them into CHR RAM or overlaying numerous sprites (and risking flicker).Ĭan software rendering help? Tony Hawk series for Game Boy Advance soft-renders a 3D player character to CHR RAM in real time, but the GBA CPU is also fast enough to emulate the NES CPU.īy the Super NES era: Several games were 32 KiB or larger battery RAM, and a game using the GSU might barely be able to soft-render a 3D player character, though at a reduced frame rate.

Nowadays, it's possible to make a custom mapper on a CPLD that bankswitches a large work RAM and saves to an unused area of the PRG flash. Games would have to be planned carefully to fit their state into a cheap chip. Nintendo has been known to cancel finished products such as the NES port of SimCity and the English version of Mother because replication cost would kill the return on investment. Very few NES cartridge boards (such as SXROM and EWROM) provided more than 8 KiB, and most of them were rare and/or Japan-only.

Some kinds of simulator games, like SimCity, The Sims, Harvest Moon, and Animal Crossing, have large grid-based world maps and tend to need 8 KiB just to store this map, let alone the rest of the world's state. Limitations: 8 KiB PRG RAM no 3D graphics hardware

Gradually, the cost of programmable logic (CPLDs and FPGAs) decreased to where a custom mapper could be affordably incorporated in a cartridge at volumes of 1,000 units or less.īy roughly 2020, such FPGAs were powerful enough to hold designs that outdo MMC5. Thus due to low volume, the NES scene stepped backward from MMC3 and MMC5 to discrete logic mappers such as UNROM. The NES CPU can render arbitrary shapes to pixels and send the pixels to CHR RAM through the PPU, and numerous essentially turn-based games have done this.īecause of the video memory bandwidth limit, however, it may not happen at a frame rate suitable for real-time games without blitter hardware on the cartridge.Īt times, the mapper capability achievable in the economic environment has decreased.įrom 1994, the end of the licensed NES era, to 2008, when the CIC was publicly reversed and commercial NES homebrew became viable, there was almost no demand for new NES mappers. Other limitations mean that the NES can display something, just not fast enough. Building your own clone (or emulation device) of mappers and other external devices is also possible, although this may also be expensive and/or time consuming.Ī clone or a port to a less powerful system keeps most of the game design, which is already paid for, and cuts down the design in ways that the porting team thinks the players won't care about.Ī team of amateurs with no deadline can eventually squeeze more capability out of a system than can a commercial game developer bound by opportunity cost and return on investment.Įven commercial developers in a country with a low cost of living, such as China or Brazil compared to Japan or the United States, have a time-money tradeoff biased toward time: witness the "Hong Kong Original" Famicom reductions of 16-bit fighting games, platformers, and RPGs, and the Brazilian ports of games to Sega Master System and Sega Genesis. In a commercial game project, managers have to balance the cost of solving technical problems like those listed below with the cost of exploring, implementing, refining, and balancing the game rules.Ī game for a powerful system will often be programmed inefficiently because it gets the game out the door faster. To clarify something: Some of these limitations don't mean "can't" as much as "too expensive". This could be part of why these genres took off after 1991 when more powerful hardware became more readily available. Some of the limitations of NES hardware and common mapper hardware severely limit the system's capability to perform well in some genres.
