Hyperzone only changes the color palette (every time you see some white flashing beyond the track). Easy for the hardware, but the emulator would have to filter a new image.

Yeah, the idea to upscale the underlying 1024x1024 screen won't work if the game changes the palette every frame.

Maybe the upscaling can be done with 8-bit bitmap data? Of course every group of lines of the emulator output has to use its own palette, in case the game changes it between lines.

screen mode

To be more precise, it's a 'background (decoding) mode'. It tells the SNES how to fetch and translate the graphics for the background layers, and can be specified per line. Sprites are not affected.

There are several screen modes, depending on some bits:
- 224 or 239 lines per field (basically, NTSC or PAL)
- progressive (default) or interlaced fields (most useful for BG modes 5 and 6)

Official workaround: enable Studies/Normandy (whatever that is, apparently this is enabled by default for most plebs nowadays), which allows Mozilla to fuck up with your software prefs because you no longer own your computer push the updated cert without waiting for a patched FF release.

No need to wait if you follow the steps here.

I'm trying Vivaldi, let's see how many of my extensions can be installed/substituted there.
It can even stack tabs, though apparently not to unlimited depths like Tree Style Tab.

As for email - I just use the Notifier for Gmail extension.

Previous relevant threads: SNES Hardware Revisions, SNES: Detecting 1CHIP consoles in software (maybe), blargg's SPC test ROMs

_ _ _


Today I got a 1CHIP-02 in the mail, which (hopefully) completes my SNES upgrade journey.

Previous setup:

- (2/1/3) (1992) (EU PAL ) "Super Nintendo" SNSP-CPU-01
- (2/1/3) (1993) (JP NTSC) "Super Famicom" SNS-CPU-GPM-02 (modded with physical NTSC/PAL switch, no switching via joypad button combinations)
- SNES Joypad, Mouse
- SD2SNES (Rev.E1 / 2012-02-10)
- standard SNES Multi Out to SCART cable (NTSC version)
- Framemeister (aka XRGB-Mini) v1.3 (with FireBrandX's SNES settings / profiles)
- AVerMedia Live Gamer Extreme (LGX) (GC550)
- AVerMedia RECentral 4 (viewing/recording software)

These components had some issues, some of which I discovered only after some time.

- The SNES games library is most compatible with the 'original-style' SNES units with separate CPU/PPU chips and separate SMP/DSP chips - 1CHIP consoles do show some glitches [1 2 3 4]. The only problem with the '2CHIPs' is the smeared pixels due to slower video signal rise/fall times. This may have very well been the intention of Nintendo's original hardware designers, in an effort to hide dithering even via RGB output. (The analog signals are generated directly in the PPU2 chip, so there's no way to go 100% digital unless the chips are reverse-engineered and replaced with modified clones.)

- The SNES Multi Out to SCART cable did not have enough shielding around the individual wires, so interference and crosstalk influenced the video and audio quality. The picture showed //// checkerboard lines, especially visible on areas of solid color, and the sound carried an audible buzzing on bright screens (for example on the 240p Test Suite's "Horizontal Stripes" pattern).

- The Framemeister introduces some noise to the video.
- It also really likes to operate in YUV color space instead of RGB, and afaik the conversation is not lossless.
- It converts non-standard video signals, like that of the SNES, to HDMI-compatible framerates. This means you can use a much wider range of TVs / monitors / capture cards, but some SNES frames are going to be dropped every couple seconds.


New setup:

- (2/1/3) (1995) (JP NTSC) "Super Famicom" SNS-CPU-1CHIP-02 (21,478,849 Hz, seems to go down slightly over time (1Hz per a few minutes))
- same joypad (with replacement rubber patches) and mouse
- same SD2SNES
- PACKAPUNCH Multi Out to SCART cable
- OSSC 1.6 (240p is converted via "512x240" mode to 1024x720; 480i is just passed through)
- StarTech USB3HDCAP
- OBS Studio or AmaRecTV


Notes:

- The 1CHIP-02 is the last original SNES version that outputs RGB and CSYNC out-of-the-box, no soldering required.
- The new Multi Out to SCART cable removes the checkerboard lines and the buzzing (unless I turn up the volume to absurd levels).
- The OSSC removes the noise / framerate issues of the Framemeister. It also has much fewer settings that need to be adjusted to get a perfect picture. It also doesn't modify the incoming frame rate, which means no more dropped frames - if only the LGX would be able to reliably capture the SNES' raw progressive video frequency.
- Hence the need for the USB3HDCAP, which can capture video >60fps. Note that you need to download and install the manufacturer's drivers before connecting the unit to your Windows PC to avoid the automatic driver installation. Also, don't bother with any "Thrillness" drivers that are rumored to be necessary.
- OBS Studio and AmaRecTV can display the video from the USB3HDCAP even at non-standard framerates.
- For some reason I never noticed the WRAM refresh "jailbars" on any of these SNES units...

I'll try to record some comparisons tomorrow.

Is that why that Super Mario World Star Road level where you have to Spin Jump through blocks to reach the exit at the bottom has fairly loud buzzing when played on a console???

The first level in this video? I'll have to test that, but probably not... unless you mean the last screen with the white clouds.

Some video recordings and screenshots. (The videos are compressed with the Lagarith codec. All done with NTSC consoles.)

In the shielded vs. unshielded SCART cable comparisons, the 'checkerboard' pattern changes every frame. It's best visible when pausing the videos.

_ _ _

One thing I forgot to mention: In the driver settings for the USB3HDCAP, set HDMI/DVI bandwidth to 125% and RGB24/RGB32 color range to limited. The fps can be set to 60.098813897441.

Came across a lecture that mentions byuu.

https://youtu.be/5cfvL3cMnz4?t=1272
http://multicores.org/blog/from-silicon-to-simulation-and-back.html

[...] As part of the lecturer's research, a Verilog model of the 6502 CPU was implemented in an FPGA and used in a real 6502-based system instead of the original 6502 CPU to perform real-time fault injection experiments. Following the talk, a system with FPGA-implemented CPU will be demonstrated.

The lecturer, Michael Engel, is professor for Embedded Systems at the Hochschule Coburg. His research focuses on the areas of fault tolerance, embedded system efficiency and embedded operating systems. In his spare time he deals with old Unix systems and operating systems and tries to keep his small private computer museum running.

Unfortunately only in German.

We already have die shots (1 2); the problem is finding people who can separate, photograph, digitize and understand the layers.

My doubt was whether there's any interest in documenting the differences between each PPU revision. According to Silicon Pr0n, those shots were done by mcmaster, so I guess I'll get in touch with him. It'd be nice to preserve all CPU and PPU revisions (and maybe find out what's unique about PPU2v2).

Before destroying a rare PPU, maybe someone can put it on a breakout board and analyze it that way... But I'd guess that most changes were for streamlining and cost reduction instead of bug fixes.
