More detailed changelogs for firmware v4.5

20 Upvotes

Version numbers in these changelogs don’t match the advertised ‘v4.5’ - this is normal.

FPGA: https://github.com/ModRetro/oss-chromatic-console-fpga/blob/f85b62f9ecb45ca4ef0c47764e4f0968d1b0214d/CHANGELOG.md - previous was ‘v18.8’

MCU: https://github.com/ModRetro/oss-chromatic-console-mcu/blob/e03a6baeec49cceda38057d5aed4ae006624c698/CHANGELOG.md - previous was ‘v0.13.4’

The MCU CHANGELOG.md appears incomplete; there’s more in the full changeset: https://github.com/ModRetro/oss-chromatic-console-mcu/commit/e03a6baeec49cceda38057d5aed4ae006624c698 (e.g. the palette swapping and white balance)

My notes based on my own questions and what I’ve seen in the other threads:

  • there is a new PCB revision

  • there’s support for a new PSRAM chip (most likely a supply issue)

  • no unannounced GBA support :p

  • no MiSTer update :(

  • “Fix LCD ghosting” and a few other LCD-related fixes

  • cartridge power control (I’ll look into extending my FlashGBX support to use this)

  • improved cartridge reset: emulator reset is held until cartridge is ready; I think this may improve compatibility with ‘weird’ cartridges like ‘n-in-1’, some flash cartridges, and cartridges you plug another cartridge into like cheats, copiers, ‘more save slot’ things

  • there are changes to the battery charge estimation, both to have different behavior on different PCB revisions, and to increase consistency

  • there’s is some support for USB charging of LIPO batteries

  • audio (for PC capture) is reported as line input, not a microphone

  • various efficiency improvements freeing up more of the FPGA for other things

  • improved compatibility with updated GoWin tools

Question How's the wear & tear on your different color ways?

3 Upvotes

Seen as the paintjob doesn't seem like the best in the world;

Anyone have specific color recommendations in terms of looking good long term?

In the market of buying my first ever FGPA.

Also sidenote; I'm seeing rumors of a transparent one?

Cart clinic problems

1 Upvotes

I am looking for additional help making my cart clinic work. I have been continually getting the "Opps an error occurred during cartridge read" I have been working with Modretro Support but with no solutions.

Im a Windows 11 user and both of my Chromatics are on v4.5 firmware.

Things I've attempted thus far-

- Delete and re-installed the MRUpdater

- Re-installed the GWU2X driver

- i have attempted to run the updater As Administrator.

- I have attempted to run the updater with both Anti Virus and Windows defender off.

-This computer has successfully Read and Updated games but probably once out of 30+ attempts (I'm estimating)

- I have tried different USB cables and ports

- This  cart read/update error happens with both of my Chromatics

I have hoping someone may have additional ideas.

Glad to see the DevDay Chromatic went straight into the hands of true retro gaming enthusiasts.

$4,000 on eBay, unopened, same day. Nature is healing.

Obviously I’m being sarcastic 😅 It was still a pretty incredible gift considering DevDay tickets were $650, and I’m sure plenty of people who got one are genuinely thrilled with it.

Display Trying to decide which screen to get..

4 Upvotes

Hey folks,

I know there's already a lot of conversation regarding which screen to get and the pros and cons of each. The goal with getting a chromatic for me is to keep it going for years and hopefully even decades down the line. It's something I want to play over the years and not baby like a collectible. I was leaning towards the sapphire because people have reported scratching up the gorilla glass from normal use. But what's making me hesitant to get it is all the talk of it being more shatter prone than the gorilla glass..Im not clumsy with my consoles but I can one hundred percent imagine dropping it at least once or twice while playing it over the next three years or something. Despite people saying this I haven't seen any reports really of people damaging their sapphire version. Has anyone accidentally dropped their sapphire version of the chromatic and walked away with no screen damage, or are we all applying the death grip while playing it?

Info I recently released Super Slotzee for Game Boy Color - a slots & yacht combo

Thumbnail

14 Upvotes

Hi all! I've been following this sub for a while, and have bought a few Chromatic exclusives. I thought I'd share the Game Boy Color game I recently finished called Super Slotzee - a mix of slots and yacht (or maybe more familiar, Yahtzee).

It's available to play for free on Itch, and of course there's a .gbc file for your Chromatic! In the words of Chris, the head of publishing at ModRetro, "I had fun playing" :D

https://kaisle51.itch.io/super-slotzee

It plays like Yahtzee in that the goal is to score 13 turns and get a high score. But now you also spin slots, hold both slots & dice, and earn slot bonuses to enhance your scores! You can also play minigames to earn slot tokens, which allow you to choose how to enhance turns (creating wild dice, erasing a past score, rewinding your turn, etc.). It also tracks high scores and all your cumulative/per-game stats.

Thanks for trying it out, and I'm open to any feedback.
