Spolous (made by suppon) has been released and it's actually pretty good, you can play it directly in your browser too.
https://twitter.com/Suppon2014
At first I thought 'this starts off slow and very easy' but the difficulty curve is great.

Also on Itch.io (play it in your browser or download for Windows).

Otomedius G (Gorgeous!) and Otomedius X (Excellent!) (Both Japanese) Title Updates added to the Downloads section.
Note these are only the game patches and not the complete game, they are of useful if you're emulating the games in xenia (xenia-canary supports Title Updates).
I only managed to get Otomedius X (Excellent!) working with the Title Update (xenia-canary), all the DLC and extra characters work fine (I will not be posting any DLC as you can still buy it on Xbox live), the game has some graphic glitches on some stages.
What are Title Updates?
Games on consoles like the Xbox 360 get updates to patch new things like DLC and to correct issues with games, because the DVD is read only, Xbox live downloads the patch and patches the game in real time when you run it.
Otomedius G (Gorgeous!) was to patch the menus for the two extra DLC characters.
Otomedius X (Excellent!) patch changes a lot of the weapon strengths, fixed some slow down on some stages and balanced the game difficulty.
Also more fan music from kaguyadepth, CD coming soon! (20th December 2020).
逆ディウスⅡ～望野のアフーゴ～ (Gyakudiusu Ⅱ ~ bōya no afūgo ~), translates as Reversedius II ~Mochino no Afuugo~
Here are two fan made games by Ace from the old GHW forums (Ace9921 - https://www.youtube.com/user/Ace9921).
Gradius The Dark Armada and Unofficial Salamander 3, see the Downloads Games section for the files.
Please note that these files are old (the games were made in 2009), not made by me and may not work correctly on modern systems, you're on your own with these old games.
Bubble Memory was a commercial failure and died too easily.
https://en.wikipedia.org/wiki/Bubble_System
Some Konami games like Gradius, TwinBee and others in the arcades used Konami Bubble System for game storage, Gradius did have a later rom release and went for over ¥1,000,000 the last time I saw one for sale.
However there may be hope for all the broken Bubble System boards out there, an interesting development I just found out about, a Bubble System emulator board for original Bubble System games called Bubbless.
Also here's some images of the box the board would come in, it's quite cool as it looks the same as the original metal box the Bubble System is housed in on the original game.
https://illegalfunction.wixsite.com/bubbless/bubbless - Translated to English
It's not cheap (¥58,362 about £430 or $557) and is currently out of stock but it is a way of making original boards work again if you can get hold of one.
https://www.beep-shop.com/ec/products/list?name=Bubbless
At this stage I don't think I will get one as my Gradius board currently doesn't work at all, even if the Bubble Memory is broken, you should still get the warming up message and Morning Music, I don't a display or audio at all, maybe in the future I'll look at getting it looked at.
I just read their site specs and it says that to use this board you need a working Bubble System to copy the Bubble Memory, so it will only work if you either have a working board or know someone who can read the roms from their board.
Good for preserving a working board but seems to be a huge oversight as if your game is dead then you would have no way to copy the roms onto it.
Good for copyright protection, bad for game preservation.
More fan art added, this time some nice art by GeoSwordRX35.
Added information on English translations for the new CD collection from Konami.
It's not out until next year (20th January 2021) but it is looking to be a very nice collection of tunes coming on ten discs.

Hey, I finally got around to doing something Gradius related.
I've scan the UK edition of NES Gradius manual, box and cartridge scan, 600dpi and a few 1200dpi scans too.
Also scanned the Japanese release too, I was inspired.
It's in the Downloads - Hi-Res Scans section.
26th January 2020
Otomedius English Translation update, nothing added to the game, however I've decided to add some of my source help files and scripts on how I made the translated version patch files (also included in the download), these may be of use for others to follow in patching the game further, I may add more in the future.
Now that Otomedius original arcade game no longer works in Windows 10 (worked fine in Windows 7), this is not that much a surprise as the original game run on Windows XP Embedded, this make make it impossible to continue the translation effort until MAME catches up or I have an old machine for just one game.
Otomedius has been in MAME for some time (not working), hopefully once it's working it should be a little more easier to progress with the translation effort.
4th January 2020
Cleaned up the downloads game section, added some game ISO images for the Saturn, PlayStation, PlayStation2 and PlayStation Portable.
Added all the demo and beta release roms I could find for various systems.
Cleaned up some broken links, removed some no longer needed thumbnails, made the whole site wider (it's now 1200px rather than 1040) as screens have got bigger and wider over the years.
12th October 2019
Changed all the magnet links to torrent files, hopefully this will sort out the downloading issues.
21st September 2019
Last year I bought a secondhand VHS video recorder with a build-in DVD recorder, I then spent a few weeks capturing all the Gradius videos I have.
In April 2019 I encoded all those videos on the PC to h265 HEVC, as they are still a little too large for the site, there will be torrents just like the Salamander anime I put up earlier.
These releases also include 300dpi scans of all the artwork with each release.
They are in the Downloads - Movies and Music - Game Simulation Videos section
8th September 2019
Well today I thought I would go through the site code and clean up a few things.
So I've archived some of the What's New section.
Also moved the GHW site back to the GameStone domain (I have an SSL certificate for GameStone), the gradiushomeworld.co.uk links will still work however they will get redirected to the GameStone - Gradius Home World section..
GameStone has always been the master domain anyway.
3rd June 2019
R-Type Final 2 Kickstarter has started.
9th May 2019
Fans come to the rescue again.
Imagine playing Gradius III on the Super Famicom (SNES) without slowdown!
Well now you can, amazing work on (in my opinion) the best version of Gradius III has just got better.

How can Konami mess such a simple thing up.
The Arcade Archives (PS4) games contain all the different releases of a game (Gradius II GOFER no Yabou also has Vulcan Venture as well as other minor rom revisions).
So this version in the UK will only have Vulcan Venture and not Gradius II GOFER no Yabou.
So, the collection doesn't have all the different releases of each game, no physical release and as a collector I have other ways of playing these games legal or otherwise (eg. Gradius II GOFER no Yabou - JAMMA PCB, PlayStation, PlayStation Portable, Windows 95, PS4 Arcade Archives, MAME and probably many others).
All they had to do is package the Arcade Archives games with a 'choose your game' select screen and that's it but they chose something else.
So I don't think I'll be buying this unless something changes.
8th April 2019
I've re-encoded the Salamander Anime in a more up to date codec (h265), files are much smaller.
However as they are still too large for the web server so I'm using a torrent magnet link again, if this works out a have a few of the game simulations videos too.
UPDATE:Fixed the magnet link as I copied it wrong from the older release (wrong hash).

I've notice some old forum members are joining the John Smith Legacy Discord server I also run, you're more than welcome to join but please note that that section is really only for the John Smith Legacy Minecraft Resource Pack, if your a Minecraft player and use the JSL pack welcome.
However so as not to confuse the current members of the John Smith Legacy Discord, I've decided to start a Gradius Home World Discord too as I guess the forum wont be coming back anytime soon.
23rd January 2019
All dynamic scripts have been updated to the newer way of doing things, so the site should be back to where it was (minus the forum).
Remove lots of external broken links in the Fan Games and Links section.
I'm thinking about maybe starting a Gradius Home World Discord, that would be much easier to manage than starting another forum and it does allow real time chat too.
21st January 2019
Sadly the forum has been taken offline, my host no longer supports PHP 5.6 which the old version of vBulletin used, also it's not compatible with the newer PHP 7.2.0 or higher.
Now the choice is to find some new forum software or just shut it down, I've decided to go with option two as the forum was pretty much abandoned anyway, with Konami all but given up with Gradius it's hard to update a forum with very little posts or user interaction.
Also some of the site is broken too, I'll try to sort the scripts out over the next few weeks, this is quite a pain.
UPDATE: Fixed the download script so at least you can still get the games, as for the rest this will take some time to learn the new way of scripting.
