I bought a Playstation Portable a few months ago and wanted to learn how to build programs for it. Instead of just building some sample programs, I ported an Another World/Out of this World engine. github.com/internalregist… #psp #homebrew #retroprogramming

@8bitnews1 I'm not retired and I haven't won the lottery either. I've just been busy with life I guess 😅. Thanks for the sharing.

There are many homebrew 8bit machines. But @IntRegister took it serious and built a fully functional game console. Details here: 👇 8bitnews.io/r/a1/homebrew-… #8bitnews #retrocomputing #retrogaming #8bit #homebrew #diy #gameconsole

I've been working on a Z80 high-level assembler in my free time for fun and I've decided to put it on github: github.com/internalregist… #z80 #assembler #RetroComputing

@masterlinkueibr NTSC allows for about 240 visible lines (PAL has even more), most games on the SNES opted for a 256x224 pixel resolution. So depending on the CRT and its settings you could see vertical bars.

Why almost every SNES games have those weird black borders and why no one talk about it?

Wanted to work with an AY-3-8910 sound generator I bought a while back and decided to make a video about it: youtube.com/watch?v=srmNbi…

@RancidBacon Yeah it is a bit of work and unfortunately not my day job, still I wish I could update more often. Thanks!

@IntRegister Nice write-up! With the amount of effort you clearly put into both the development & write-up it's no wonder there's a bit of time between your updates. 😄 Thanks for sharing your work. (Saw it via HN.)

Just wrote a blog post about a project I've been working on. Yet another video game console, this time FPGA-based: internalregister.github.io/2021/08/08/Ano…

Back to electronics (I hope), bought 2 TMS9918A Video chips and they look brand new and the text is oddly different on the two, could they be fake? 🤔

@leiradel been there...

So much pain and grief because one assembler fills space with 0x00 and another one with 0xff...

@leiradel @FlohOfWoe I don't know what you need exactly, but if you want to see how a Z80 works at the clock cycle level, you could use a VHDL simulator, for example, with something like the T80 cpu core which is a VHDL Z80 core. It should be accurate enough.

@FlohOfWoe might get one of those while waiting for the single-stepped Z80 :) m.youtube.com/watch?v=BJkZbc…

@retrohouruk @ZxSpectROM I would love to get a Neo Geo AES, but it's crazy expensive, not only the console but the games too

Which retro machine do you really want for your collection? #Retro #retrogames #retrogaming

@SmartykitE Thanks. And sure thing, you can reach me at internalregister(at)gmail

@IntRegister Interesting console! Would love to discuss in more details via email

For those curious on how the video works on my console, I finally finished writing the post about it: internalregister.github.io/2019/09/29/Con… I also wrote an online simulator as a companion for the post: internalregister.github.io/2019/09/29/Con… #electronics #retrogaming #retro

@SarahJaneAvory Happy Birthday!

@JohnKennedyMSFT The only reason this didn't happen to me was because I would always get car sick, so I couldn't play with my Gameboy in a moving car.

Had to share.. #GameBoy30

@shano002000 I use a microcontroller to serve as an interface between the CPU and the SD Card, the CPU just requests simple commands like "open file", "read file", etc. And the CPU puts the read bytes into RAM. But using a ROM cartridge does make it a lot simpler.

@IntRegister this was a really good read. I'm beginning to see how everything works now. I'm planning on building a simpler game console that loads graphics in game cartridges(ROM) as i still don't really get how the sd card is interfaced. Thank you so much

@SarahJaneAvory I was curious, how do you know if your games are not too hard to beat but not too easy either. Do you have get some people you trust playing them before release and tweak the difficulty depending on their input?

A few people have asked when the post on my video game console's video system would be out. It's almost finished, one of the reasons it's taking so long might be because a part of it will be interactive.

@leiradel I've heard about Antstream Arcade on the GameHut youtube channel, it seems awesome. Congratulations on your new job. 🙂

Plot twist: I now work for Antstream Arcade!

@shano002000 Yes, I've actually already started writing it. I just haven't had much time for it lately. I'm gonna try to finish it by next week or so. Thanks for the interest 🙂.

@IntRegister Hi, any plans on making a follow up on this series? i'm very interested in learning as much as possible especially in the video generation circuit

Just wrote a new blog post, this time on how the CPU Board of my homebrew video game console works: internalregister.github.io/2019/07/26/Con… #z80 #retro #homebrew #electronics
