New on the blog: after about three tries I've finally managed to get my head around the SNES memory map. At this point I'll be able to produce linking scripts to order, though for now I'm mostly making the same decisions as a particular tutorial does.

Soon I'll get to write some actual code, and maybe after that I can write some code that will actually _run on the console._

Now that the TopSpeed TechKit with its #assembler is out in the world, I'm considering porting the #TASM and #MASM code in one or two of the open source #EPOC16 apps over to TSASM.

Hardly an urgent project, but it would mean that the apps could be built with one #compiler ecosystem with a single project file.

Of course, the code would still be restricted to the #16bit world, but it's no worse off than we already are in #Psion land.

Just seen the preview of Crash Magazine 17 and it's a great issue for #puttycadpresents #puttycad and my awesome friends #psychicparrot #richpea #100tinsoldiers & my son who doesn't have a gamedev handle yet :) #NoSpoilers #gamedev #indiedev #retrodev #zxspectrum #8bit #pixelart

AFAIK this is the most complete version of the #Psion SIBO C SDK.

It includes multiple versions, the full TopSpeed C including the TechKit, all the documentation I can find, plus some handy config files for you to get started in @DOSBox_Staging and with VS Code.

There is evidence online that, by 2012, Psion were fine with the SDK and HDK being distributed.

Have at it!

I'll also be making a "2.21" with a few fixes, such as checking for includes properly.

I'm going to boldly say that my 2.21 version is the one you should use, but of course I'll distribute the older versions. I've definitely had projects that will compile with 2.00 but not with 2.20. I think these projects are more likely to compile with 2.21.

IT LIVES!

Please welcome to the world the #PsiDrive, a #Psion USB SSD Drive using a #RaspberryPiPico.

This works with the SSDs that were used with the SIBO range of computers, including the Series 3 and MC400.

This prototype can only be used to dump SSDs, but future versions of the firmware will let you write to RAM SSDs, and future versions of the board will let you write to Flash SSDs.

I'm struggling so hard with this social media activity concept again, but oh well. I'm streaming NES game development in a bit and probably ranting about stress and stuff. https://www.youtube.com/watch?v=CV7aXIT5Lh4 #retrodev #nes #envtuber

Calling all #RetroComputing friends:
I’ve designed a simple web site that should run on almost any browser that supports html3.2. However I’ve had reports of it displaying poorly on a #crt I wondered if people could send me a photo of my #website homepage on their system so I have some references.

Wrote up a summary of the past year on Hackaday IO (@hackaday) because it was rattling around in my brain.

OK, *now* I'm going to rest.

#GBDK-2020 v4.2 is out!

Thanks to heroic work by Michel Iwaniec GBDK #NES support is capable of building Black Castle (by @User0x7f@twitter.com
) to run on the NES

Updated to SDCC compiler to 4.3 (up to 10% size/perf gain)

Built-in #GameBoy Color Hi-Color effect support (via png2hicolorgb + an example project)

https://github.com/gbdk-2020/gbdk-2020/releases/tag/4.2.0

GBDK is an #opensource development kit for the #GameBoy/Color, #SMS, #GameGear an now #NES

Streaming some chill NES game development. Mostly just trying to update the player sprites, I guess. https://www.youtube.com/watch?v=G3df_JyFyCc #envtuber #gamedev #retrodev #nes

Well this is fun!

This counts as #retrodev, right?

Meanwhile, works continue on the 8-bit ports as well. The UI was redesigned (and still is in flux) Lots of optimizations, but still some numeric precision issues.

The IBM PC 5150 (8088 4.7Mhz + CGA) was also juggled into this version (I'm cooking an EGA version for faster 8088s and 286s, using the geometry for the 32-bit engine).

Some optimization later and the GBA version of Derelict is shaping up nicely. Still a lot of improvements to go (and still zero ARM ASM), but it shows some promisse.

Incidentally, I no longer can build for Amiga or Atari ST on my Mac (had to replace the SSD and the toolchains won't build anymore).

What is your favorite text-based game written in #BASIC?

Rules:

1. Any dialect of BASIC is valid.
2. "Text" can include extended characters in common use in the 8-bit era.
3. #interactiveficiton or #IF is valid, but the scope of the question is wider than that.
4. No sprites or graphical tiles.
5. Modern games that meet this criteria are valid.
