I shall be there with my trusty MZ-700 (recently upgraded to run Quick Disks) and my also trusty MZ-80K (showing some games by IMDb creator Col Needham). It's going to be a great weekend with lots and lots of very awesome and interesting machines.

This was a pretty cool find. A decent platformer game in the same vein as Manic Miner etc on the Sharp MZ-80K. Not that I'm particularly good at it yet but this has some really nice animations using the Sharpscii graphics.

On commence avec le stand de @CousinHubert12 qui est encore venu partager de fantastiques ordinateurs japonais (j’ai pu tester un homebrews MZ 700 que j’ai), mais aussi des modules de karaoke japonais atypiques !! #RGC2025

『ロポコ for Steam / Nintendo Switch 』各バージョンともに結構難易度は高めです。しかしヒントはちゃんと用意されていますし、ニャッピー先生を誘導する個所などを除けば基本コマンド総当たりで解決するはず・・・レトロゲームの雰囲気を強く意識した本作ならではの謎解きをお楽しみください！

#Sharptember A chance find among a bunch of tapes I won in an auction turned up something pretty interesting, a compilation tape of games written by Col Needham (the creator of IMDb) and likely his master tape from which he sold his mail order games. Here's his game "UFO Attack".

#Sharptember If you replace the CG-ROM file in the emulator with the Japanese one you can play Japanese MZ games with the correct graphics showing. Here's Namco's Galaxian demonstrating the much coveted single pixel graphic character that was not available in the western ROM.

#Sharptember The popular "Greedy Gremlins" game, this time for the MZ-80A. I recently rescued this from an official Knights tape - I don't think I realised there was an MZ-80A version until now! It makes use of the 80A's inverse display quite a lot.

#Sharptember One of the more popular assembler environments on the MZ was Avalon's program Zen. It's a simple line editor and here I show a few of the commands. E to enter lines of code. P which prints x number of lines of the program and T to target a line of the program. /1

Here you can see I left a piece of the program out, the INC HL instruction. I target the line where I want that command to be inserted and use the E command to enter it. The program simply writes the letter A 1000 times to the screen memory directly, beginning at address 53248 /2

Finally the A command will assemble your program to the address mentioned in the LOAD command at the start of the program. The optional 'V' command prints the code to the screen as it is assembled. /3

#Sharptember So what makes the MZ-80A a bit unique amongst the other MZs available in the West? Well, it had double the VRAM. This meant, unlike other 8-bits, you could scroll the screen up and down as you can see in the video. Lines of BASIC could come back onto the screen! /1

Another feature (as shown in the video) is the ability to use inverse video by reading a particular memory I/O address. This was a feature where the whole screen was affected. I did however, write some machine code which got around that limitation: youtu.be/sOHSl4sJ0Zo?t=44

BASIC Interrupt on the Sharp MZ-80A

This is an example of writing an interrupt which alters the screen ...

#Sharptember ! And here is a small bit of gameplay from the excellent adventure game Ropoko for the MZ-700, the English language version that will be available later this year. It's a tricky puzzle adventure with some bold big sprites which will keep you entertained for ages!

#Sharptember Many people may not have noticed that the popular magazines of the time, e.g. C & VG and Your Computer were covering the MZ machines quite well. Having been through many homemade tapes from eBay auctions it's clear what one of the most popular type-ins was. Defender!
