I see nothing wrong with repros. Playing on the original hw is best, and for things like translated JP-only games it's either that, emulator, or flashcart, and for a casual player a flashcart may be too expensive. Selling Repro's on eBay is piracy. Period. Seriously what is this? http://www.ebay.co...

Most SHVC-CPU-01 2/1/3 units are not fixable. If one chip is damaged, they might all be damaged. Oh well, I got replacements for all chips. Challenge accepted :) A screenshot would be helpful, though there is no guarantee that a SNES/SFC can be fixed, the fact that you can boot a game at all sugges...

Most SHVC-CPU-01 2/1/3 units are not fixable. If one chip is damaged, they might all be damaged. At any rate "black and white and garbled up" suggests your connection first. This is the same kind of effect you would see if you connect the composite or the Y (luma) pin to the Green pin on a...

I'm working on some SNES Mouse stuff so I'm adding mouse support to the Carbon input driver. However! Since I don't have access to the canonical windows build at the moment I'm not quite sure how it's supposed to map the mouse input. At the moment I'm just feeding mouse coordinate deltas to table[m...

I'm bumping this just out of interest. So my previous post was mostly taken from photos and the two non-working SNES's I had. I've since acquired a 1/1/1 SFC CPU-01 from Japan (production 6) and a GPM-02 (the one without the "APU can" but still the separate chips) and discovered that the A...

I'd like to advise not watching this video at work because the "background" is basically cropped Princess Peach hentai. I try not to be a prude, but there's always been a really seedy, gross underside to the ROM hacking community that makes the whole thing look bad. If I ran RHDN, I'd kic...

VeriSNES shows promise in this regard, however keep in mind that: 1. The way the FPGA NES projects work are not 100% accurate (tiny underclock by 0.164167% (60.098 to 60)) for speed to avoid creating latency in upscale, this may also be true for SNES 2. The SNES interfaces are 5V, while FPGA's are n...

Mario-Chip1-SFX.jpg I scaled this down from my iPhone and quickly drew an arrow to where it makes contact on the PCB Incidentally the Super Mario RPG cart also has one in the same place. So it might exist on all expansion-chip carts. That could also explain why these carts are more finicky since th...

I tested with the multimeter and got continuity there. Maybe My soldering iron was too hot when I put it back. It seems to go to pin 69 of the Mario chip. Edit: I figured out! It's a faulty inductor! If I have undestand what I read, the original inductor is 0,1 or 0,2 microhenry (I just can't know ...

It is really interesting how the fine scrolling is used for wavy effects.

148.5 MHz is presumably for 1920x1080 including blanking: 2200*1125*60. But you'll probably have to slightly slow down the Super NES clock as well, as the S-PPU normally outputs 60.1 Hz, not 60.0 Hz that the HDMI spec expects. Most games use double strike mode, which renders 262 lines of 1364 cycle...

I think web browsers are the big holdout for PCX support. There is a specific reason why web browsers support what they do. If only one web browser supports something (eg APNG, MNG), and nobody else does, the feature gets dropped. Originally web browsers only supported JPG and GIF. The former was l...

Just curious, but why do programmers pick python over java? My university just switched the two CS level I and level II pre-major classes (known as the elimination courses; weed out people trying for CS major) over from Java to Python - everyone (faculty and students) have collectively rolled their...

I think the fact that even I know ASM (albeit, after loads of help) invalidates any argument that says it's too difficult to understand. :lol: That's because High school and College programs that involve programming use Java (and have been since 1998.) Looking at the local University's webpage they...

If somebody is making a program for measuring the CPU to APU clock ratio, it would be interesting to run that tool on different consoles and to collect the results somewhere (or did anybody already do such a thing?) the result might vary depending on things like... - master clock (PAL vs NTSC) - ac...
