iiinova — where your digital self keeps evolving

Disassembling the amazing #MSX version of Nemesis (Gradius) and just figured out what this mysterious little routine does!

openMSX emulator showing the game playing with the Twin Bee ship instead of the Vic Viper, and a bell instead of a power-up capsule. Alongside it is Ghidra showing the disassembly of a routine that searches cartridge slots for ROMs with a sequence of bytes that signifies Twin Bee.

Don't do it! It is highly addictive. There are just so many cool machines to implement, and they each have dozens of amazing games to get working, and each one is like a little celebration when it appears on screen. (see you soon)

Enjoyed your Vice City retrospective thanks. IMHO it's greatest design achievement was making the road races challenging and cover increasingly larger sections of the map. IV and V didn't do this, and I often felt lost and disconnected from the world as a consequence. Hope VI does this right.

I wrote a PlayStation emulator earlier in the year. It doesn't run everything I want yet, but it was great fun and I learned a lot of interesting things along the way (don't look at SPOILERS.md if you ever intend to write your own one day) github.com/howprice/hop...

Montage of four classic games running: Ridge Racer (red car on track with blue skies and all the arcade HUD), Final Fantasy VII (Cloud, Barret and Tifa celebrating a victory in battle), Crash Bandicoot (staning there looking dumb), Metal Gear Solid comms screen also showing the various debug views the emulator features: VRAM visualisation, SPU, DMA and CDROM state.

You're writing an Amiga emulator? I found lots of demos and some games require quite accurate timing. Have you implemented the copper using Toni's recent RE of Alice?

Mel Croucher knows a bit about the history of games, and he can write! May I suggest backing GAMERS 3: Play On Demand (3 days remain) www.kickstarter.com/projects/mel...

Apple are the only possible way I can see to unstaggerise the columns of keys on the typewriterless keyboards of the world. Just need to find their ear somehow to persuade them it is for the good of all.

Packed up my boards for VCF. I'll be giving a talk on ArduinoX86 on Saturday, at 11AM I think the demo will blow your mind, come check it out! #retrocomputing

It has a scriptable debugger which can be handy.

2. Right-handers only: Remapped Step Over and Step Into to F4 and F6. Spent a good chunk the past 20 years with my left arm crossed awkwardly in front of me on the F10/11 keys. Took a week to get used to.

1. Learned Visual Studio's "Force Run To Cursor" feature. Edit some code. Right click and force run to cursor. Debugging it immediately. All breakpoints ignored en-route.

Stunt Car Racer on the #Amiga is an absolute timeless classic. A true rollercoaster ride. It could be the best game on the system. Here it is playing from an "original" IPF disk image on my emulator at 60Hz. What a game! youtu.be/Ffuilx1kkI0

I am very pleased to release Aira Force 0.9.2 This release emulates blitter fill mode, which is used by many more demos than games it seems! It also fixes lots of gnarly Amiga timing bugs. howprice.itch.io/aira-force/d... youtu.be/2H6l_wrfTDY #Amiga #Emulator #Debugger #Disassembler #imgui

Added floppy disk/drive/controller emulation to my #Amiga emulator. This allows OS friendly software to run. Some more hardware features are needed to support lower-level disk access (DSKSYNC register mainly) youtu.be/Cwxz6Z6vDtc
