you have gone through the tech portal...
welcome to the world of tech... thiiiiiiiiiis is where i talk about my most favourite thing in the world. technology! i have been really interested in it for all my life! ^_^


the YM2612 is a 6 channel FM sound chip developed by yamaha and was made to be a stripped down version of the YM2608. it was mostly used in the sega genesis and various arcade game systems.

it includes:

- 6 FM channels
- 4 operators per channel
- 2 interval times
- a sine LFO
- analog stereo output
- patch compatibility with yamaha DX/TX synthesizers
for channels 3 and 6, the operator frequencies can be set independently, making dissonant harmonics possible.
channel 6 can also be used as a surrogate PCM channel by enabling the 'DAC Enable' register, allowing 8bit samples to be played, however the YM2612 does not provide any timing or buffering of the samples so it must be done in software.
it can sound like this:

Toy Story - Main Menu

(if you have javascript disabled you can click on the song name and listen to it there!)

or like this...

Cover of Dirty '64 by Tobikomi

or even like this.. ^^'

Sonic Eraser - Versus Mode

...well at least its better than nocturne from sonic chronicles... right? right??? really just depends on how you use the chip! the possibilities are endless!!
i mostly like this sound chip because of nostalgia reasons and also cause i just really like fm synthesis! i think it is really cool =w=
some of my favourite composers/artists who utilise the YM2612 are:
- tatsuyuki maeda
- john tay
- savaged regime
- look mum no computer?!

the pc-9800 series is a line up of computers manufactured by NEC from 1982-2003. they were originally intended to be used for business purposes but game companies took over!!! the pc-98 series is notorious (afaik) for the cool awesome pixels visual novels and adventure games.... corpse party and touhou!!

model details


soulgen is a fake keygen i made as a joke.. there is really nothing much to it!
really i just made it to practise my visual basic skils... that's it
the whole premesis to this is to just.. generate a string of letters, numbers, and symbols from a predetermined mask.. yeah
the music used in this is here, however you may realise that it sounds a LOT more different.. thanks to open mpt and renoise playing the file at different speeds and me not being able to find out which was at the right speed...
and actually i think it sounds cool. lets just say it was intentional!
the picture is from white clarity, but i edited it to just put the text at the end.. in chiller font lolol for the xtra epix factor

the code was lost to time unfortunately... and i don't think i will ever find it again :[
this was made for the bbc:microbit! in around 2018 if i am correct.. and programmed in python! (NOT MICROPYTHON) how to use this? hook the microbit up to a speaker, shake it around, and hear your fate be told to you by the robot... SAM!
the reason i made this? for a project in school i had to do in computing! and i won first place with it B] awww yeah
sometimes i feel like i was a lot more smarter in 2018 than i am now.. or maybe i am just burnt out and/or lazy
how it worked was veryyy simple. there is an array of phrases to be said and a random number is chosen which correlates to an index number in the array! that's it! and also an 8 is displayed on the tiny little LEDs. this was made for the microbit 1.3 or maybe the 1.5 i cannot remember correctly.
thinking back, i should have added some sort of like thing that tells you what the answer was just in case the user did not have crocodile clips to spare bwabwabwa
