Now that the MSX/CPC and Spectrum versions of the game are done, I can now put some time into my plan to bring Chibi Akumas to the Enterprise!
The game will come on disk, and require 128k.
Graphically it will have the colors of the CPC+ version, just without the hardware player sprites... but don't take my word for it, take a look at the game running in the screenshots below! (Early Alpha build)
As it'll be 99% the same as the CPC version, I'm expecting the game to be done in a couple of months!

Cool !!! Looks very good, and it runs on the EP128emu :smt041 :smt041 :smt041
If you have speed problems and if you did not already do, load 0ch to port 0bfh :)

I didn't know that one, so I will do it... does that cause any compatibility issues of any kind?
That said, the speed is pretty good, when everything is done I'm expecting it to be slightly faster than the Amstrad CPC version, because the Enterprise has a slightly faster cpu, and the interrupt handler is simpler, as the Ep128 color changes are done by the hardware... oh and screen positioning is easier, because the lines on the Ep128 are below each other, so easier to calculate!

As I remember 0Ch does not cause any compatibility issue, it just disables the additional waits, the default is 04h, which adds wait to z80 instructions as I remember for make closer to the EP64 speed, with the default setting EP has similar speed to CPC. 0Eh/06h could cause loading problems if you load from tape :D

The processor runs at 4Mhz also on EP :)
The port handling is very complicated on CPC, especially keyboard, and Sound.

Ok ,thanks for the info.. that gives me some confidence in what the setting does before I start messing! I've turned it on, and I'm not seeing any problems... I've done a side-by-side compare, and the Ep128 version is noticeably faster than the CPC version!
I was under the impression that the amstrad CPC CPU ran at an effective 3.5 mhz or so, but I'm no expert, so I'm not sure, anyway, the game is going well, and I'm not expecting any problems getting the game working!

While the Z80 in the CPC runs at 4 MHz, all memory and I/O port accesses have to be synchronized with a 1 MHz clock. In the Enterprise, only the video RAM (segments FCh to FFh) and the Nick I/O ports are subject to clock stretching, although the slowdown is greater than on the CPC. In other words, EP128 code in normal RAM can run at full speed, while the CPC treats all memory as if it was video RAM, even if faster video RAM than in the Enterprise. A few examples of how many cycles it takes to execute Z80 instructions on the CPC:
NOP 4 cycles
INC HL/SLA A 8 cycles
LD A,0/CP (HL) 8 cycles
JP/POP/LD HL,0 12 cycles
JR 8/12 cycles
CALL 20 cycles
DJNZ 12/16 cycles
LDI(R) 20/24 cycles

it runs on the EP128emu
How could you try it? Where can the game be downloaded?
I've checked the link but haven't found EP download section.

The game is under development phase, we got pictures as preview :-)
I think we have to wait a bit :-)

Sorry, I misunderstood, I did not try, I just saw the pictures :)

All, who supported Keith at Patreon, obtain beta Enterprise version of the game.

Cool, so it means you have a beta version :) , and it means the full version will be available soon, I ordered 2 :ds_icon_cheesygrin:
-
as I see this runs in 4 color mode. looks cool!!
-
full version will be available soon
On the Keith website written:"(Planned release Nov 2018)"
as I see this runs in 4 color mode. looks cool!!
And on the screen at one time ≈12 colours. Some ingame levels have dynamic palette changing.
-
what about the fps? it uses some hw (lpt) tricks for the scroll?

Yes, his 1st plan was that, but he mentioned that the progress was better than he expected :)

FPS... Not very good, that I can see on that gif:
(https://s8.hostingkartinok.com/uploads/images/2018/06/fa7339fbbbc042d54ad37579ba0500fb.gif)
Maybe, release will be more speedy.
-
ah bullet hell! very cpu-intensive.
maybe you can try to half the resolution, vertically (lpt doubling) and horizontally (lores mode)
-
Hello there!
Just to let everyone know, you can now download ChibiAkumas FREE for all systems (including Enterprise!)
Remember, the game needs 128k!

PS. Some people may be waiting for physical copies, please contact PolyPlay directly if you are, I don't have any information at this time about what they have shipped.
Thanks,
Keith

please somebody make a snapshot, because I cant use img files

Keith56 wrote the name of the shop in the very same sentence you started to quote.
-
Cool, the game is too hard for me, but looks cool, and moves cool :)
I will check Polyplay about my order.
Thank you very much.
-
The game is too hard for me too but looks cool.
At our next Enterprise meeting (club) we should try the multiplayer mode. Two players can perhaps kill the crazy enemy.
-
Please could no-one else buy from polyplay until Geco's order arrives.
I'm sure Polyplay will eventually deliver, but they seem to be being slow and I don't want people disappointed! (they've never done an enterprise game before)
As a little teaser, here's some screenshots of a little 'Minigame' I've made based on the same game engine... but less 'bullet-hell' and more 'phoenix/space invaders'... it's called 'Tragical Chase' (a parody of a certain PC engine game!)
I'll be releasing it free in 2019, but I'll give it now to anyone who's already ordered from polyplay to make up for the delay receiving your game, Just PM/Email me with your polyplay order number and I'll send you the link!
-
this is a cool game and great project, thanks for it!
sad, I dont like these game type, because it is too hard. the old side scroller shooters are hard to me too, but playable.
but I know, bullet hell is a liked game type.
maybe an option for easy mode?
and maybe with energy bar and not lives...?
-
The game has an easy option in the settings menu, you can also set the game to 250 continues
Despite being 'bullet hell' this is not a hard game to win... During testing I often played the game at 10x speed - you could literally win the game blindfold with 100 continues
-
Awesome game! Good graphics, good sound, very nice! Very good to see professional game also released to our favorite machine! Thanks!

Reading Guide (http://www.chibiakumas.com/guide/) can help, if you think it is too hard :-)
There is a snapshot with Ramdisk, including the full game.
-
and great thanks because Keith56 explain how to do a z80 compatible game using winampe emulator
Merci beaucoup ;)

is anyone got anything from Polyplay? Least a answer for a questions?

I got an answer for my question when i submitted it 3rd time :D
Sebastian has problem with his disk drive, he is not able to copy the disks in this moment.
I suggested to use MSX to do it, or if he has a PC with FDD.
He asked if i want back the money, I told to him, i have time...

Currently I only sent two times :-)

This is the problem :ds_icon_cheesygrin:

Yes, a fourth time is indecorous...

Now I got a invoice and delivery note :ds_icon_cheesygrin:
