Volume 3 of Learn Multiplatform Assembly with ChibiAkumas is out now!
Volume 3 is in the same format as volumes 1 and 2. The first chapter is the assembly introduction which is basically the same as Volumes 1+2 (So you can read Volume 3 without having read the other volumes)

Volume 3 covers MIPS, TMS9900, SuperH, IBM370 and PowerPC CPUs

The book is around 50 pages longer than the previous volumes, so the price is slightly higher due to printing costs - In many countries I'm actually making slightly less money on this book.

The book is out now in B5 sized Hardback and A5 sized paperback... A4 paperback is also available Here

Buy Volume 3 Here!

Due to piracy problems and relatively low sales of Vol 2, I'm not planning to offer a Kindle version this time (I'm pretty sure there's bot scripts automatically ripping off the new releases), however I will be offering 'Buyers remorse' PDFs, and any of my patreons who signed up before 2024 will be offered a PDF copy too - I will post an update about this in the next couple of months once the dust has settled from the book release.



My Books are now available in Hardback and Large Print A4!
In response to many comments from readers, I'm now pleased to offer my books in Large print A4 size! I'm also able to offer Hardback in countries where amazon offers it

I've also released my updated 2nd edition of volume 1 (I've been giving out this as part of the buyers remorse offer for a while)

Check them out here: https://amzn.to/3hgETuM
My 1st book covers ASM programming on Z80, 6502, 68000, 8086 and ARM
My 2nd book book covers ARM Thumb, 65816, 6809, PDP-11 and Risc-V CPUs

The Large print versions can be a little hard to find... the links are here:
Vol 1 A4: ttps://amzn.to/3T8WzFG

New for 2022! My 2nd book is out now!!
Buy my Assembly programming book

My 2nd book is available now on amazon! Volume 2 of "Learn (more) Multiplatform Assembly with ChibiAkumas" is now turning up on Amazon stores near you now!

Volume 2 is the same format as Volume 1, but covers 5 new processors: ARM Thumb, 65816, 6809 PDP-11 and Risc-V CPUs

The first chapter is the beginners introduction, based on that of Volume 1 but with various improvements and corrections, and with a new extra section covering sound. The processor

sections are the same format as Volume 1. Overall Volume 2 is around 10% larger than volume 1 (299 pages)

Link to the UK store: https://amzn.to/3tkPwjC

Or search on your local store, it should show up. Please note it may take a day or two, I can't buy the print copy in japan yet :-(

If you decide to buy it, please try and buy the print version - I will offer the 'Buyers remorse' PDF for print copy purchasers like before as soon as the 3 month 'amazon kindle

exclusive' period ends (around july)... it would suit me to only offer print going forwards, but Kindle brought 20% of my profits last time - which is too much to turn down.

I'll do a video showing it off once I manage to get my hands on a copy over here in Japan!

About ChibiAkumas...

Chibiko is not having a good afterlife! Being killed by divine intervention, and banished from the underworld is all par for the course, but now a hoard of noisy, ugly, cliché, and badly drawn monsters are invading her land, and causing a ruckus in her castle!

Chibiko is not the kind of vampire who takes this kind of thing lying down! Its time to "Rise from your grave", and use unholy magic to annihilate the monsters, and wipe out this invasion at its source!

ChibiAkumas is the ultimate in 8-bit bullet hell action! bringing the lastest arcade style action to the 80's Z80 computers, and bringing new life to long dead computer systems!

Whether you're a fan of the Amstrad CPC, the MSX2, or the Elan Enterprise 128k, the ChibiAkumas series will bring new,exciting and unexpected games to your platform... with plans to extend to more Z80 systems in the future!

As well as games, I'm running a Z80 Programming Tutorial series, in which you can learn all the tricks and skills I learned during development, and as the games are opensource, you can build your own games based on them!

Warning!: This game is comedy fiction which contains graphic violence, bad language and religious themes which will be offensive to some people. the games rating is R-15, if you do not shows like "South Park" you will not enjoy this game
This game is not suitable for children - if you think a psychotic monster is a good role model for your kids I think you need to re-assess your parenting methods!
I do not condone or encourage any of actions portrayed in this game ! This is FICTION. if you cannot tell the difference between what is acceptable in a game and real life you should not be playing this - Killing people and drinking their blood is NOT COOL!... I despair that I have to point this crap out, but it seems I do

Some of the images on this website have had their colour enhanced for artistic effect and to represent the intended appearance of the character, I do not want to mislead people as to the standard of my game, so these images are marked with a red cross
