@jedimb There's a gimp plugin I made for that: https://github.com/bbbbbr/gimp-rom-bin

For many rom types they can just be drag and dropped into GIMP, edited and then re-exported.

The source should also give a sense of the tile data formats.

More advanced rom hacking and resource editing may require disassembly, especially in cases where sprite and background data have been compressed.

@maxoakland As others mentioned in the replies for the linked post, try Kagi.

As a paid service it is more likely to be aligned with the user (customer) versus ad based services where the user (us) is the product being sold to advertisers who are their customers.

They have a implementation now where you are pay, get anonymous tokens and can use it while logged out. Results are pretty good.

#gbdk (and #bbstudio) is adding new NES tilemap layouts!

By default we use 1-screen layout for simplicity - but this has scrolling artifacts.

The NES can do better. 2kB VRAM allows H / V layout to limit artifacts.

And cartridges can also provide VRAM for 4-screen layout to remove them completely.

#gbdk2020 #gbstudio #nesdev #retrogaming

New release of #gbtoolsid: 1.5.2

@Pierrec Fantastic!

@harryfk Love the slightly ambiguous texture

@dansup @aspensmonster Something to consider: I solved a similar question of how to balance "quality" vs improved discoverability for more obscure entries (in a different domain) by doing:

- "featured + ~5% random shuffle/mix chance per entry"

This way there is plenty at the top of what many people may be looking for. Along with giving more obscure entries a better chance at visibility that may just pay off if the right person sees it.

@DamonWakes @Jeltron Ha, I'm in a similar camp generally. My days of running (and patching/upgrading) servers and platforms are hopefully over. 😅

Reviving thread with news in latest fediverse report:

Taken time but seems people have stood up independent parts for all the network. Plus other relay/etc news.

And -the "Graze" company mentioned provides service for bluesky accounts to build custom feeds... now allows monetize the feeds by with ads (only to subs). They's only marked with "#sponsored" hashtag.. kinda insufficient? Third parties selling ads instead of the platform is odd.

The riveting (😄) GBC 2x speed update to #MBC7 accelerometer chart

- 2x mode on graph (green/orange) normalized to 1x mode scale to easily compare
- Seems to require same time for data to stabilize in 2x mode
- Range of noise larger with 2x mode, and an offset for flat x/y once it reaches stable

@aparrish Cool! It' very readable.

Looking forward to someday adding detection for it to gbtoolsid 😜

Save the date, the #GBCompo25 starts next month!

Bring your skills or learn new ones to create a game, a tool, a #demoscene or a music ROM for the #GameBoy and compete for over $5000 (and growing) in prizes!

@SantiagoCrespo An annual no-electricity/no-internet day sounds amazing. Sign me up :) :)

The game idea seems like a cool theme, great name to start with too.

@SantiagoCrespo Spooky. Been in a couple long blackouts and it's a strange feeling for familiar places.

Made a quick port to GBDK-2020 of msx_qrcode (which is a fork of Nayuki's code).

So it's an easy way to add runtime generation of QR Codes to a #gbdk based #Game Boy game.
