Found a SNES at a local store for $40. Is this a good deal?

I've been browsing the last few days, and I've looked at SmartMedia cards. They are 5V compatible, have a very simple interface (possibility of real-time access), and very cheap. Ideas?

I thought of modifying the code to support NES. That was scary! He uses awfully messy code + old version of delphi. (I don't know pascal too well so I may be wrong).

The problem is that it there are only 256 unique tiles, which is like 1/4 of your background. You're gonna have to use a highly empty/repetetive image.

Here's NESrev 32k version, fully compiled, for all of ya to leech:

All you ned is the java runtime.

I don't think 27c512's will fit without some rewiring. Why can't you just use a 27(c)64 for VROM and a 27(c)256 for PRGROM? No rewiring needed, just solder two sockets, insert eproms and cart ready for use.

That can't be, cuz I used only one pattern table.

Sorry, that was color 1, not 0.

I was writing a simple test with sprites that uses NMI. Well in FCEU and Nintendulator the sprites are displayed as a single dot of color 0 at x and y position in OAM.

I don't get why it wouldn't work. This is highly recommended to do this between the PPU writes and the $2005 upload in VBlank, however I couldn't say exactly why is that needed, nor why it wouldn't work. Many games writes $3f, $00, $00, $00 so I always do the same without asking questions. Chris Co...

I've got an idea: with the NES's many quirks, why not make a list of things that one has to do to make a game run on a real NES? This will answer the questions of the many n00bs here. I'll start with what I know: - Wait two V-blanks on startup before doing anything with the gfx. - Read $2002 before ...

Hello, with some more dumb questions. I don't know how to make this work properly; in each emu i tested it in (FCEU, Nintendulator, JNes, and no$nes) yielded diffent views of sprites 0 & 1. I guess this is some quirk of $2003 and $2004 that the more mature emus are emulating. MainLoop: lda #1 st...

Is it possible to generate random numbers on the NES? I have read that the noise channel plays random frequencys (is it so? english not very good). But can you read the random values and use them in your programm?

Well, CGBide (with modified syntax.txt) has all i need.

I use CGBide (site's down, but some french gbdev site has a local copy) with a modified syntax.txt file.
