Fortune telling with mahjong tiles.

When three tiles line up, it's a 暗刻 Anko
When all four tiles are aligned, it's called 暗槓 Ankan
When a pair is formed, it becomes a 対子 Toitsu
There is also a secret combination.

It's not real mahjong.

Is it possible to reproduce the sound of past game consoles?

Is it possible to reproduce these sounds with a picotron?

I have almost no basic knowledge of how to combine operators or create algorithms, so I'm just trying to figure it out.

It has been my secret desire for many years to be exposed to FM modulated sound production.
In particular, I have a history of admiring sounds like the Mega Drive (Genesis).
Of course, the songs that make full use of not only FM sound but also PSG sound are nothing short of amazing.

Non-editable instruments

Sat, 23 Mar 2024 15:25:47 UTC

I cannot edit after ID8 in the instrument edit.

https://www.lexaloffle.com/dl/docs/picotron_synth.html#Instruments

There are 128 global instruments defined at 0x40000 by default, each 512 bytes.

Are the 128 instruments mentioned in the specifications scheduled to be available in the editor? Currently there are up to 25.

Also, when multiple envelopes are set to "DATA" mode, the window extends outside of the screen.
Scrolling is required in the same way as for the waveform configuration windows.

PELOGEN2 is released!

Sat, 24 Feb 2024 00:25:29 UTC

The distribution URL is here!
https://bitchunk.itch.io/pelogen2

What tools?

PELOGEN2 is a 3D modeling tool created on PICO-8.

Because it was created for such small specifications, it is not suitable for overly complex and large modeling.

In today's era of large-scale, detailed works, what would you create with this small-scale 3D modeling tool?

I think there is still value in being able to express creativity within limitations.
Even if it imitates something that exists in reality, it is precisely because it is low-poly that an unrealistic and creative world can be created.

Tutorials will be added to the devlog from time to time.

You may have questions about things you don't know about how to make or features. I would appreciate it if you could create a thread in that case. It's easy to deal with, and others can use it as a reference.

Features etc.

Data management

You can manage data while viewing the 3D model.
Up to 16 data can be saved.
The data can be exported to text, so it is virtually unlimited.
You can organize and rearrange data by copying and pasting.

3D view (when editing the model)

View that can be rotated to any angle
Enlarge/reduce/slide in the Z-axis direction
View rotated along grid (every 22.5 degrees)
Vertical flip prevention

3D modeling editing

Add triangular face and manipulate vertices
JOIN selects vertices and combines them into one (equivalent to merge in blender)
Move selected triangular face, rotate 90 degrees, change color, duplicate

Other features

Sample code copy function
Assembly mode (next version planned)

PELOGEN2

CPU meter toggles with Ctrl + O

Thu, 01 Feb 2024 05:58:03 UTC

CPU meter can also be switched using Ctrl + O. As per the PICO-8 manual, originally only Ctrl + P is required.
This specification seems strange to me.

Recently, it has become possible to implement an option to operate in combination with Ctrl.
For example, when developing tools, there are times when you want to use the Ctrl + O keys to open files (data).

Development of new PELOGEN

Mon, 29 Jan 2024 14:00:42 UTC

I previously created a 3D modeling tool called "pelogen".
It was designed to run on pico-8 with a minimum amount of data, and with its 16x16x16 vertex coordinates and one-stroke triangulation, it was almost exclusively a tool for myself.

This time, the specifications were revised from there, and the tool was created with an eye to making the data a bit larger and easier to model.

The vertices will be edited in such a way that triangles are added, instead of the specification of adding vertices one by one.
And we will set a color for each face.
You can JOIN the vertices of each triangle to simplify vertex movement and build complex shapes.
You can duplicate selected triangles and rotate or flip vertices by a limited number of angles.
Data management of the model becomes more intuitive and easier to understand.

Development is about 90% complete until ready for release.
Data import/export, sample code, and model size limit checks remain.

Match 3 in development (Part 3)

Wed, 18 Oct 2023 02:03:28 UTC

This is my own public blog posted on pixivFanbox on August 28, 2023 at 13:40.

I am able to get some time before bedtime, but I don't have much physical time and often fall asleep right away.

Match judging and then erasing blocks

We also create a direction to make the matched and erased blocks fly away.
However, this leaves the block full of gaps.

Match, then drop the top block

There is no falling direction, but the erased area will be filled with blocks.
However, this also leaves a lot of gaps. It is necessary to make up for the gaps.

Compensate for the topmost block so that there are no gaps

Place an additional block at the top of the erased area and drop it.
The falling direction has also been added.
It is becoming more like Match 3!

Redetermine the match after a block falls

After a block falls, erasing the already aligned blocks becomes just a tedious element.
We now need to judge matches other than the block-flip action.
It will be exhilarating to match in a row!
(Since the previous work description, the block falling process has been radically reworked.)

Completed this time

✔Actual replacement of ingredients.
✔Match production.
✔Disappear when matched.
✔Compensate for the missing part. Drop new ingredients from above.

Plans for next time

✔Counting of matched ingredients.
✔Select 7 out of 16 ingredients to make them appear.
✔Standstill judgment and shuffling process.
Time is up and the game is over.

Game ends when the number of times has expired.

Reset P8SCII cursor movement by newline code

Sun, 28 May 2023 06:18:31 UTC

Horizontal alignment is reset when a line break or tab is inserted in p8scii.

The example below expects the first line to start at the beginning of the first line after a line break.
Also, the tab position seems to reset the shift cursor.

5*5px custom font 「傾きかな」(Katamuki kana)

Thu, 25 May 2023 14:08:03 UTC

When you see the default kana font, you might think that you could create something a little better.
But then you realize that it was a kind of provocation for creators (or designers).

Why the tilt?

Hiragana can be quite difficult to express in 5x5px.
One answer to this problem is a slanted design.
This allowed us to secure a space, albeit a small one, per character.

Notes

chrcode 144-153 are used as discarded kana.(ぁぃぅぇぉァィゥェォ)

It is quite difficult to maintain hiragana visibility at small sizes. As a desperate measure, I tilted the characters and crammed them into that area.
