Defending the 6502 arch honour
So at Revision, a gauntlet was thrown down from Team Mega Drive to Team ( if there actually was one ) SNES. The Mega Drive being a 68K so the Amigians patron console, while the SNES is 65816 representing the 6502.
The demo can be seen here https://www.youtube.com/watch?v=OeGdJk5zb6c
Given the SNES has 3.5Mhz 65816, 128K and a very nice PPU, lots of ROM space, hardware multiplier/divider + DMA channels and very accurate emulators ( a problem the MD people suffer ) It should be possible to melt the MD ;)
Sadly the SNES devs are not up to the task, anybody from the C64 demo teams willing to step up and plug the gap?
Being able to split the Data and Program banks should allow data to be packed more tightly and then you can move the DP(ZP) and where you want should push Speed code into Hyper code.
The never used Interlace Mode + HDMA should be good for some NUFLI type shenanigans. |

The SNES is a fine console with many great games, but yeah, there are things, like those 3D parts in Overdrive 2, that wont happen without something like an SFX chip, because of what White Flame stated above.
That said, lol @ "honour" of a processor. |

also MD has one of the Z80 things in it! SNES has SPC-700 which is basically a 6502 as well.
Sure but you don't make a LOROM when making a demo, you go HIROM and get 3.5Mhz all the way. Also 128K is the Work-RAM not really a Scratch Pad ;) I mean its double what we have..
Go SA-1 then and have a 10Mhz 65816? but that wouldn't really be fair to the MD XD |

If you want to beat Overdrive 2 with a SNES demo, you should cheat using a module with Super FX chip. ;o) |
