So am I just burning the 240p_MegaCD_USA (Disc Image File) to the CD? When I download it to my PC I get a whole bunch of files and folders, etc. Or am I supposed to burn everything that was downloaded?

Just burn the disk image file (.iso or .bin & .cue)

Is there a room in the SNES 240p test suite for a 512x224 pesudo transparency test pattern?
Some games like Kirby 3 and Jurassic Park use this technique to fake transparency on a bad CRT with a poor Composite signal :).

I did consider it early on, but ended up finding no use for it. What use case do you imagine?

This image can test the sharpness of a CRT with various SNES outputs (Composite, S-Video, RGB).
I guess people can just run Jurassic Park on a flash cart.

Well, it can be used to check rainbowing and such on NTSC signals (PAL doesn't appear to suffer from rainbowing, as far as I can tell).

But the already existing checkerboard test does that job, too :p

I know it has been a while, I've busy for the last few months with this project that will be integrated into the 240 Test Suite.

Here is a small description of what it is:

Code:
MDFourier is an open source software solution created to compare audio signatures and generate a series of graphs that show how they differ. The software consists of two separate programs, one that produces the signal for recording from the console and the other that analyses and displays the audio comparisons.

The information gathered from the comparison results can be used in a variety of ways: to identify how audio signatures vary between systems, to detect if the audio signals are modified by audio equipment, to find if modifications resulted in audible changes, to help tune emulators, FPGA implementations or mods, etc.


And this is the kind of output it can give, comparing a Sega Genesis Model 1 VA3 vs a Sega Nomad:

Please check out http://junkerhq.net/MDFourier for the full documentation, interpretation informatiom and downloads.

*MASSIVE* release right there. Thank you so much for providing such a tool, it will be of immense utility, especially in the Mega Drive/Genesis community.

For now, as detailed above more consoles will be targeted later on.

Can anyone here provide seller/retailer information to purchase SNES and Genesis physical cart with 240p Test Suite?

For the Wii and GameCube, is the SD Media Launcher from codejunkies reliable for running 240p TS?

Thank you for any feedback.

You can use an everdrive, or buy one from these (they kindly provide the service and there is no business relationship)

https://www.retrocircuits.com/product/240p-test-suite/
https://megacatstudios.com/collections/ ... test-suite

(They both have both versions)

Today I finished adding Super Game Boy enhancements alongside the existing Game Boy Color enhancements. (Screenshots in this Tweet.) Once I release the SGB version, owners of a Super Game Boy accessory will be able to order 144p Test Suite on a Catskull 32K cartridge by choosing Custom ROM. (Also no business relationship... yet.)

Compared to the Super NES version, I had to leave these out because of SGB limits:
Color Bars (present on GBC), SMPTE Color Bars (present on GBC), Mode 7, Alternate 240p/480i

But just about everything else is present:
PLUGE (including PLUGE Contrast), Color Bars w/ Gray Ref, Color Bleed Check, Grid, Linearity, Gray Ramp, White & RGB Screen (with custom color), Motion blur (replaces 100 IRE), Sharpness (including brick wall), Drop Shadow/Striped Sprite, Lag Test, Manual Lag Test, Scroll Test (horizontal and vertical), Grid Scroll Test, Horizontal Stripes/Checkerboard, Backlit Zone Test, Sound Test

240p Test Suite (NES, GB, and GBA) v0.19 is out

It took another heroic compression effort, but I freed enough space to add a Super Game Boy border and colorization to all tests that would benefit from it. Not a lot of changes on NES and GBA though.

Highlights on all platforms:

  • Stopwatch: Bolder digits
  • Help: Standardize phrasing: "stuck pixels", "hide or show", "start or stop"
  • Help: List patrons as of release time

Highlights on specific platforms:

  • GB: Super Game Boy colorization and border
  • Backlight zone (NES, GB): Increase starting size to 2 pixels
  • Color bleed (GBA): Fix frame # covering everything
  • PLUGE Contrast and Vertical scroll (GBA): Center pattern horizontally
  • README (GB, GBA): Explain rationale behind "144p" and "160p" titles

Behind the scenes:

  • Help (NES, GB): Integrate Johnathan Roatch's faster DTE compressor written in C
  • Linearity (GB): Compress with reflection
  • GB: Improve incruniq tilemap compression
  • GB: Compress font and large graphics with nibble-wise Huffman coding
  • GB: Move variables to HRAM; other code size optimizations
  • GBA: Use a more common makefile
  • GBA: Specify each PNG's conversion settings in a grit file

Download: GitHub release | ROM and source zipfile (553 kB)

I plan to consider MDFourier tone generation once I get a chance to look at the Genesis and Super NES tone generators.
